SLP Dual Tip Tailpipe for 2008 Tahoe

[felixgun]

So after reading all the threads I could find about a resonator delete/adding a tip, I found my best two options were the SLP Dual Tip and the Volant Super Tips and here are the cheapest places I could find online.

The SLP is only 116.96 with free shipping here:
http://www.lmperformance.com/53163/27.html

The Volant one is almost 3 times the price at 323.45:
http://www.carid.com/2008-gmc-yukon-exhaust-systems/volant-exhaust-85243.html

TWO HUNDRED dollar price difference?? Can anyone justify getting the volant one over the SLP one? The only difference I see is on the Volant one, the dual tip is welded onto the main pipe whereas the SLP one is bolt-on. NOT worth $200 extra by any means. Thoughts? I'm about to pull the trigger on the SLP Dual Tip but I need some motivation. I'm just looking to get rid of the ridiculously ugly resonator on the nnbs vehicles and something a little cleaner/better looking then stock.

:popcorn: nice find!!! I've been looking into this exact same thing! Subbed to get more info :)

[2 E L O]

Holy crap! Just get the SLP one....then since it's bolt on you can install it yourself, too.

The price of the Volant is ridiculous....I almost bought my entire catback system for the price they want just for the resonator delete! Ridiculous.....

[crazycrew]

That's the same one I've been looking at Felix.

I wonder how it's going to change the sound. :hmm: I'm not even sure what the resonator is for other than maybe sound reduction. :shrug:

...and I couldn't find the info on the website but how long does that "sale" go on for the SLP. I notice it's about $13 less than normal.

There's a video of it on one of the threads and it sounds good. I forgot what tahoe/who put the video up, but they also had a CAI (Which I also plan on getting at the same time as this tip) so i'm sure that made it sound -just right- :Handshake:

I work in a corporate office so i'm not trying to rumble my way into the work parking lot either. Just a nice low start up sound and a cleaner look. And I don't know, when I bookmarked it a while back it was also $13 more and it's the cheapest now as i've ever seen it... might have to pull the trigger real soon.

I know! The price is absurd... i'm glad i'm not the only one that thinks that. Guy that works an office down from me has an nnbs avalanche with a whole gibson cat exhaust and paid less then that volant super tip.

So regardless of the bolt on, I think i'm gonna go with the SLP one and get it welded on at th the same local place I got my last tahoe's flowmaster muffler welded on at for like $40. well spent i'd say...

[07Burb]

:hmm: How can I get the purchase past the wifey without many questions since we haven't budgeted this in :hmm:

[jd08]

I have the SLP kit and love it. It is an easy install and looks really good when done. It does give you a little rumble on start up and when you get on it but when cruizing down the road it is quiet like stock.

[felixgun]

Ah good info to have. Did you get it put on before or after your CAI?

the SLP one felix

[Volant1]

The main cost differance is 304SS vs 409SS, Its just like any exhaust system you will pay more for 304 but it will not yellow or rust like 409. The 323 is why were no longer making exhaust systems times are tuff and people are not spending money like they use to so instead of running a cheaper product were putting exhaust on hold for a while. If you are just looking for a res delete I would head to a local muffler shop and just get a nice set of tips and a small pipe put in around here you can get it done for 50 bucks. just my .02

The SLP would be nice cause then I guess you could run any exhaust tip you wanted.

[k9lovr]

Just ordered this...Have been on the fence as well and the thread helped me make the choice....

[07Burb]

Thanks for the pics Dave! That looks great :waytogo:

Also, thanks for the insight Volant. I was actually thinking about this tonight and thinking along the same lines as you where you could create your own thing even cheaper than the SLP unit for almost nothing. If you know how to weld you could do it even cheaper than the $50 you said just by going to your local parts store, getting a little bit of pipe, and a tip and you can accomplish the same effect. Obviously, though, if someone was to crawl under your vehicle they'd notice that it wasn't an SLP or Volant product but rather a driveway job but how many people crawl under your vehicle to check that out?? :shrug:

[BlackedoutLT3]

I have the SLP as well and actually got my dad to by one as well for his 10 tahoe. Really easy install only took maybe half hour or less. Like Jeremy said had a little more rumble at start and does have a little more noise from the exhaust when cruising but not much. I put that on before the magnaflow. Def looks a lot better and well worth the price.

Sweet thanks for replying. Yea I was thinking it was kind of cheap too.. a little too cheap. But at the same time, I wouldn't want to waste that kind of money just for nothing. That's pretty much why I started this thread to get responses from people and to see if it was worth buying... and you bought two! looks like this is my next mod... :Handshake:

So are you saying there is a chance that the SLP one will yellow or rust?

[Volant1]

If they can crawl under than the truck is too high, thats my motto anyway lol, You dont have to weld the system on you can flange the pipe to clamp over the factory, We clamped ours because when it comes time to sell not everyone likes the thunder from down under, I keep every factory part I remove to give the new owner the option to keep what they want aand toss what they dont, than again I look like a hoarder! Does anyone need the roof from my F150 rag top install? Wait I might need it someday nevermind.

So are you saying there is a change that the SLP one will yellow or rust?

maybe this will help out
T304

T304 stainless is generally the highest material grade currently used for exhaust systems. It is an aircraft-quality, 16-gauge stainless containing 18 to 20 percent chromium and 8 to 10 percent nickel, also known as austenitic stainless. This means that the material is highly durable and it will never rust. It is very attractive, and even after extended use, can be polished to a high-shine finish. It also has the lightest weight of any of the material grades because of its high chromium content. T304 stainless is the perfect choice for the vehicle that will be owned for an extended period of time, and/or needs to stand up to rugged use or challenging weather conditions. It's also the only choice for the consumer who simply wants the very best, or is using their vehicle as a show vehicle. T304 systems automatically add to the value of the vehicle, and the appearance is exceptional. Because it is the finest material grade available, it also has a higher price point. This material grade frequently carries a lifetime warranty, depending upon the manufacturer.

T409

T409 stainless is the next grade of stainless available, and is probably the best known and most popular, also known as ferritic stainless. T409 is a low-carbon steel that is at least 12 percent chromium. It is a rugged, durable, long-lasting material grade offering a variety of finishes from dull "mill" finish to a high-shine finish. In extreme applications and harsh weather conditions, it can eventually show signs of wear, such as surface rust, but the core of this material will remain solid. It offers a high-value, attractive material selection at a more affordable price.

"So are you saying there is a change that the SLP one will yellow or rust?"

I have had mine for over 2 years and no rusting.. just a little behind the dual tips it turns a little yellow but not much but that is under the car you can see it just from the rear. The tips stay chrome. Just after the winter you are going to need some metal polish because of all that winter grime that gets caked on.

This is what I was saying about a little color difference under the car

[felixgun]

Thanks for the info Brent... the rear of your truck is lookin clean btw. Two questions. Did you weld it on or just do the bolt on/clamp method provided with the SLP tip? and off topic-- Did you put the esky rear appliques above the esky tail lights to match? btw the esky 3rd brake light would match those tails and really set it off!

@Volant1 - Thanks for the info I had no idea of the different grades of stainless steel... you learn something new every day.

[Volant1]

Once the oxide layer is gone any grade stainless will start to go, but like any product if you take care of it you will get more life ouy of it. If you have a little rust behind the tips it could be due to the tips rubbing on the main pipe which would take off the protective layer I would sand it and just paint the pipe. If the tip is a dual wall it will not tint because the inner pipe gets all the heat which is why the yellowing is worse in the split.

[BAMA_LTZ_HOE]

The price for the SLP isn't bad at all since I just paid a muffler shop to do my resonator delete for me with a 4" chrome tip for $108. The only reason I didn't get the SLP is because I didn't want a dual tip. There isn't much difference in the sound. A little more sound at idle and full throttle but cruising speed I cannot tell a difference. I did mine while the wife was out of town and didn't tell her. First day she drove it she came home and said "does my truck sound different to you"? I told her no but later told her what I did.

:lol: sounds exactly like what I'd do! :lol: That does look really good. My end goal with my exhaust is to do exactly what you did but with duals (one on each side) and a Magnaflow muffler.

Question: If taking the resonator off doesn't really change the sound to speak of what purpose does it really serve?

No just clamped them on with the clamps that came with it and haven't had to retighten them at all since install. No still have the stock Tahoe Appliques. Really don't even notice it at all. I really want to get the Esky 3rd brake light it is one of my next mods.

haha that's hilarious... i hide my mods from my gf too... she thinks I spend too much $ on my car... which is true but i just can't help it... it's so addicting...

Ah ok. Well you car is black so I couldn't tell if you had the rear Appliques. I have been thinking about doing the true esky tail light/rear applique mod but I'm still working on a few other things before I get to that... it looks good with just the tails though! You should def post pics when you get the esky 3rd brake light.. it's gonna look great.

It's there because the resonator looks so darn good:) Actually, I guess they did it to get the tone they wanted. To me it sounds better without it. Sounds more like a stock Denali or Escalade now.

They cut my stock pipe just after it makes the turn down over the axle. Then they put a couple of bends in a new piece of pipe and welded the tip on. The tip is a 4" angled, rolled tip and it is 12" long with a 2.5" inlet size. Here is a picture under the truck. I had them get it to where the tip comes out at about a 45 degree angle. I didn't want it coming out parallel with the ground.

I installed my SLP tip about 2 months ago on my 2011 Tahoe LTZ. It took me about 45 mins to install and it looks and sounds great. You can deff tell the diff in tone and it sounds like you have a mild performance exhaust when you hit the throttle or have a load on the engine. It doesnt have any drone at any speeds which is nice and is quiet enough that you wont hear it over your radio. I like it so much that im not even going to spend all that money on a performance exhaust system as i dont want it to loud and i dont want to spend like $600-$800 bucks for a very minimal performance gain.

I just took these pics from my cell phone so there not the greatest quality.

Looks real good. I need to order mine before they sell out

I finally go time to install the SLP Tips and am very happy with the fit and finish as well as the sound. Nice rumble on start up and WOT but no real notice when cruising along which is what I was looking for. Install to about 35 min with a reciprocating saw and a jack for more room. Here are some pics...http://i160.photobucket.com/albums/t170/k9lovr/Tips5.jpghttp://i160.photobucket.com/albums/t170/k9lovr/Tips4.jpghttp://i160.photobucket.com/albums/t170/k9lovr/Tips3.jpg]http://i160.photobucket.com/albums/t170/k9lovr/Tips1.jpg

[bmwme]

OK I need some help.

I went to install my SLP tailpipe last night but felt like I should measure the current exhaust pipe size before I hack it off. The reason is that I have an unknown (ugly) tip on my exhaust and the resonator is already gone. Glad I did because the ID of the SLP tailpipe is 2.5" where it is supposed to clamp OVER the stock pipe. My current OD of the pipe after the muffler is about 2.6". So I cleaned off some of the grime from the muffler canister and found "GM Performance" on the can. Soooo I guess I have an upgraded muffler. I think it is this one http://chevroletpartspeople.com/searchproduct.asp?model=Tahoe&catid=3371888334227616&year=07&productdesc=Exhaust+System+by+GM

Did SLP ever make a system for the GM Performance muffler? Any suggestions on what I should do?

[k9lovr]

You may be able to expand the tip...I think it has a slit on the end

[calima51]

Hi guys,

Is there a benefit to running the tips out the side v rear. I like the rear and have seen threads on noise not being as loud out the rear. What are the cons to a rear exit, if any. Thanks!

[07Burb]

The choice of either side or rear is mostly cosmetic and what you like best. The sound will be virtually identical...

You're right...and it may be my only option.

[R_Sharpe]

Not trying to revive an old thread, but this is interesting to me. Because I want something will a better tone. I'm really picky, and I want something with a little more rumble while idleing/accelerating heavily, but I don't want something that screams out at people like a '95 Silverado (no offense to anyone). This seems like the best solution for me because I didn't want to pay $400-$1,000 for an exhaust that I might not even like, and IMO, the SLP tips look pretty boss, so... This just might be on my list of mods to come. :)
How is the installation? Hard? Easy? Do I have to cut anything? Or is it just pop the factory one off & clamp this one on?

Very easy and I made a thread on it. Felix went with a Volant tip which is a nice unit as well and probably a little bit better quality but it is also pricier. I spent $116 on the SLP assembly, $100 on the Magnaflow 12589 muffler and paid a shop $40 to weld the muffler up (I installed the SLP myself). You will have to cut the old resonator off but there are instructions that come with the SLP which make it really easy to know where to cut.

Go to my thread (http://www.tahoeyukonforum.com/forum/showthread.php?t=26309). At the end will be pics and a vid of the sound.

Yes you can just cut off the resonator and bolt on the new one but welding (which is optional) is definitely the better method IMO. Both tips looks great. As you can see Jacob went with SLP and I went with the Volant one which is no longer in factory production. You can only find them rediculously overpriced on some websites for 300+. I got mine used from John (nytahoe) for like 140-150 shipped which is a great deal. I went with this one because of the 'yellowing' issue over time. The stainless steel grade is higher on the volant then the SLP but according to blackedoutlt3 he's had his SLP tips for a few years and the tips have not turned yellow. I didn't want to take the risk and that is the only reason I went with the volant one. If money was not an option I would go with the Corsa Sport exhaust system (basically muffler, tips, and piping). But if you look at the Volant super tips, SLP Dual tips, and even the corsa sport exhaust, they all have side rear dual tips... so instead of spending an arm and a leg on the corsa sport, I just chose the Magnaflow muffler (12589) and the volant tips because i'm 'ballin on a budget'. If you have unlimited funds my recommendation would def be Corsa.

[Keanen55]

Honestly, I looked at those but found it a heck of a lot cheaper to go to my local muffler shop and had them remove the resonator and pick out a nice chrome tip. I had it all done for $70 big ones.

[07Burb]

Chrome is cheaper but has a tendency to rust out and not last nearly as long....

[outerorbiter]

Thanks R_Sharpe for bumping up thread. Great info 07Burb. Just bought an 07 yukon xl and got rid of my silverado so time to get modding. Looks like I will be going with the slp tip/resonator delete asap and changing out muffler later. Had corsa touring on silverado but cant justify that setup again with wife and kids. Just not sure which muffler to get. Dad had ss camaro with loudmouth exhaust and loved the sound.

[07Burb]

Yeah, it all depends on what sound you're looking for really. Being as my burb is the main vehicle for the wife and kid's I went with a more melow sound that wasn't nearly as loud especially since we take it on long trips as well. I definitely like my setup as the tone is really nice and has a good rumble to it but is not loud at all. I hop in the truck when I really want to roar and wake up the neighbors and blow out cobwebs :)

Chrome tip is nice but a high grade stainless steel polished tip might last longer in the bigger scheme of things... I want this thing to last at least within my 5-7 year duration of owning this vehicle. :Handshake:

[BlackedoutLT3]

I have had mine on for almost 3 years now and still looks great. I am about to pull it off though and get it powder coated gunmetal or black.

my rear AC leaks down on my tip, that may be a big contributing factor in tip life.

FWIW, a SLP tip is ~200 shipped,

i paid $322 shipped a NIB JBA 40-3043 3 inch SS exhaust, with a 3.5 stainless tip, but one of the stupid mods deleted the thread and link to the website, because he thought i was trying to sell my exhaust. :(

I actually purchased mine earlier today for $116.96 shipped.

I got my SLP installed on Wednesday evening. I must say, I'm VERY pleased with it thus far. I made a video comparing exhaust notes between the stock exhaust and the SLP Tip & Resonator delete. http://www.youtube.com/watch?v=e8oYeWWpIN4 just for reference, since most of us have it already, but still. :)

Sounds great. Mine is still sitting in the box since I discovered that the PO had a GM Performance Muffler Installed. It actually sounds similar, but the GM Performance muffler isn't as burbly, and my tip is UGLY.

[Garret813]

Anyone ever put one of these on a Denali? Right now I've got a Magnaflow muffler, I think 5x9, definetly not the 5x11, with some off the shelf tips. I'm not thrilled with the tips or sound (drone) anymore and want to change. Wondering if adding this tip set up will help improve the flow and sound?

[Zed 71]

I doubt changing tips will improve flow unless the ones on there now are restrictive (diameter, bend, etc.).

In cabin drone is due to the muffler (Magnaflow) without the resonator. Just based on sound harmonics, I cannot see how changing only the tips (not designed to control sound or greatly changing the length/diameter/bends) will help with the drone. It can change the sound as heard from the outside.

Finally had a chance to install the SLP tailpipe on my 08 Tahoe. I can say that this is one of those do-it-yourself mods that is worth every penny. Easy to install, sounds great and looks even better. 2 thumbs up in my book.

[ChevyGuy]

Going to add this along with a magnaflow muffler. Off with that garbage can resonator!

[jdskycaster]

Had a local muffler shop delete the resonator and install the SLP pipe, tip and Magnaflow (12589) muffler today on my 11' Yukon XL. Have to say this was exactly what I was looking for. Just enough added growl and the truck still sounds stock at cruising speeds from 50-80mph. Get on it though and there is a nice added rumble.

Installer at the shop was not really impressed as he thought it would be louder but it is exactly what I was looking for. This is an luxury SUV not a mud lovin' pickup truck with straight pipes.

I would encourage anyone looking for a mild sound upgrade to pull the trigger on this exhaust mod. Total cost installed for me was $295 and it will be fairly easy to go back to stock if I ever need to.

I would also add that I should gain at least a few mpg's just from the weight reduction alone:) That OEM muffler must have a couple of dead bodies in it. I could not believe how much that thing weighs.

[ChevyGuy]

I read somewhere on here that the resonator weighed about 35 lbs also.

Yep all I added were tips and a muffler and got rid of the resonator and it sounds JUST RIGHT :Handshake:

Just wanted to comment on some of the insight that was brought in here.
The SLP tips look great, as do the volant (they're basically identical)
However, if price is your main concern, and you want your res. deleted, just find a shop that'll cut it out and replace it. I know the cars aren't anywhere near similar, but my last ride was a 03 mercedes C320, and i got the res deleted for $40. I brought it to a shop, the guy cut it off, took a scrap piece of pipe he had lying around, cut it to fit, and welded it into place. So if your just looking to remove the resonator, this is a good way to do it. If you want the tips as well though, then you might as well buy the SLP set.

[clayp]

just ordered mine. The reviews here and youtube videos make this sound exactly like what I am looking for

[clayp]

well mine came in yesterday. I installed it this morning and overall am pleased but there were two little quirks - the factory exhaust is 2.9" OD. The SLP unit necks down to 2.6" where the polished tip slips over it. Using a horsepower calculator the max hp a 2.9" exhaust will support is 345hp. The max hp a 2.6" exhaust will support is 278hp. This is a major restriction and I might have an exhaust shop rework the necked down joint into a direct weld.

The other issue is there is no way to adjust the pieces to keep the tips from touching the lower portion of the fender flare if you want to use the exhaust hangar. I tried to straighten out the SLP hangar slightly to allow more clearance but the effect was minimal

[04ctd]

loosen up all your clamps and rotate the peaice over the axle towards the rear tire that a should bring your tip down

[HOE-N-IT]

Yes, you should be able to adjust it. I was able to adjust mine and have about 3/8 " clearance from the fender. It looks right and the plastic fender has not been affected by the heat.

I'm not familiar with the exhaust calculator but it probably assumes the entire exhaust is of the smaller size. Due to friction, turbulance etc a smaller exhaust for the entire length would be much more restrictive then just that one point. How often are you at maximun horsepower anyway. I doubt it is worth worring about. JMO.

it is sitting in a reasonable position and I'm gonna leave it for now:

in terms of the restriction, unfortunately the length of the chokepoint doesn't matter. The entire system will only flow as well as the narrowest restriction.

[Freddie]

Has anyone just cut the resonator off and dump it with a magnaflow muffler?

I would certainley disagree with that. Do you also believe that long tube headers provide no power benefit because the rest of the exhaust restricts the flow and negates any benefit?

Exaust length (friction), number and angle of bends, mufflers, cats all play a role. The air having to accelerate to pass the same volume of air through a short restriction is not the same as having the same restriction for the entire exhaust lenght. It probably is no more restrictive then the bend up over the axle. It also probably has less restriction then the resonator you took off.

we're not really disagreeing, but the point of max restriction determines the max flow rate of the entire tract. You can have a 5 vs 8 lane highway that won't flow anymore traffic if each merges down to 3 lanes at one point

Not true but let's pretend for a moment that it is. As stated before, bends (non mandrel), mufflers, cats all create restrictions. Why do race cars have straight pipes and no mufflers? The stock exhaust is of sufficient size where these restrictions (including the SLP tip) will still provide acceptable thru put and performance. The slight decrease in diameter where the SLP tip goes on the tail pipe is NOT likely to be the point of max restriction.

You highway analogy doesn't even come close. I'm not trying to be argumentative and I'm certainly no expert but may I suggest you do a search on exhaust design or exhaust theory?
