What exhaust are you running?

[LSJRL07]

I wonder about the drone also...

I like the sound of stock... almost sounds like it has a cam, but I just want it to be a little louder. I hate hearing ONLY engine noise when getting on it, so I am wanting to upgrade. This post has lots of good info, but one thing I notice is that I haven't read too much on the Drone inside the cab, particularly in the middle and rear seats. I had a 97 suburban with a Gibson Catback exhaust, and the drone in low-mid RPM's was pretty annoying in the middle and rear seats.

What's your input on this?

What's the best (quiet) exhaust with the most HP gains?

I have a 2007 Denali XL with the 6.2 and was trying to wake up the sound a little and was thinking of removing the stock muffler and replacing with a straight pipe and leaving the resonator in place. Wonder if that would be too loud??? I have had several S197 Mustangs and have run SLP Loudmouth, Borla, FRPP (Ford Racing Performance Products), Roush, Basani, and Flowmasters on the cars. The SLP is basically a straight pipe with a polished stainless tip and sounded the best but was really loud at WOT, and not too much drone. The FRPP had the worst drone.

Any thoughts??

Thanks

I had the muffler cut out and put a straight pipe and left the resonator there. Download this and it's a little audio clip of it starting up cold (hence why it takes a little bit to idle)

I don't think it had too much drone cruising, but on acceleration it had some noise to it.

Don't cut the muffler cut off to replace with a staight pipe. You should be cutting off that ugly ass resonator and replacing that with a resonator delete tip like SLP or Volant. Then have the muffler replaced with a non baffled straight through 22 inch Magnaflow muffler or something similar to that. Removing the muffler completely is a little rediculous, not to mention you will fail your emmisions when it comes time for that down the road.
If anythign is cut off, its the resonator you want off, not the muffler

That sounds REALLY good! Thanks! Could you get a sound clip while under load?

How much did it cost?

I am running Spin Tech over here, Great sound when you get on it and quiet as stock going down the highway no droning at all. I was gonna go with Magnaflow but the muffler shop guy said not to for a couple of reasons and told me about the Spin Techs and i couldn't be happier.

 

[Lyrikz]

I'm thinking about getting an exhaust system in the near future and wanted to see what some others were running.

What exhaust are you running?
Post pic if you have any...

2005 Yukon Denali. I put a Magnaflow on it... ITs a bit loud but sounds REALLY good.

Spin Tech

I was gonna get Magnaflow since Flowmaster has drone and bad flow, but the muffler shop guy said not too for a couple of reasons then turned me on to the Spin Tech, No droning at all and quiet as stock going down the highway.

I traded/blackmailed the car off to the dealership and got another one so I can't get another sound clip. Only was $75

Also Conor, mufflers have no effect on emissions, that's what the cat is for. The tip that was put on behind the resonator covered it up pretty well so there was no need to cut it off. Could always move the resonator where the muffler is and have a stainless pipe out the back

You're right, I got confused for some reason about the muffler. Your truck does sound pretty good I must say.

I'm getting the M-Flow 12589 installed next week. Will try to provide vid/audio if I have time.

Did*

It went bye bye The dealer will have a fun time trying to sell it as a family driver given the loudness...

 

[RoHoe09]

Got the Magnaflow installed earlier today...

$50 install. Sounds good. my resonator was removed back in January.

 

[stss95]

JBA catback sounds good and the price was half of what other catbacks were.

 

[mikeakatex5]

I just installed the 3.5" MBRP cat back kit. $311 shipped to California and 1.5 hour driveway install. Couldn't be happier.

I have a Cherry Bomb Extreme on my ride. I'll be sure to take some video today of the start up, ride, and cruising.
