I heard the magnaflow had a great exhaust for these trucks? I just did some research on their system and for $616 I might have to pass...

i didnt do the full Magnaflow cat back... i did however install a 24" (or maybe 22" inch but i thought it was 24") muffler and the truck is really pretty quiet for being a straight through design IMO... I forget exactly, but i think i paid like $80 or $90 for the muffler shipped and another $45 to get it welded up, not a bad price if you ask me.
I was going to wait on the cats till i did my LT's, and even still i am not sure what i will end up doing there... need to do more research

I have the same, true duals with 22 or 24 FlowPro and it's only loud if I get on it..they are old and have some drone, wouldnt be surprised if they were spot welded
Changing mine out for Magnaflows

tybardy,
Sounds good...Might need to just check into a muffler then before I get a full Cat system.
Anybody installed headers on their truck yet? IF so how much time and effort were needed?

i think Jenna and Max both have headers installed.... there is another thread going right now regarding this subject i think
Tybardy,
Are you dumping it right out of the muffler? It did seem pretty quiet except at the higher RPMs. Does it pop when you rev it up?
I like it but I don't want popping. I wonder if a tailpipe would help eliminate it.
Also, have you noticed any mpg gains from your mods (BB Tune, Intake, Exhaust)?
Love the rims man.

thanks thanks...
Yes i have a turn down directly after the muffler.
it only pops when i rev it up like crazy in neutral... when i have my foot on the floor driving it doesnt do it at all (maybe a small amount when i am at extra high RPM and take my foot completly off the gas).
As for the MPG's I am getting about 19 average right now. Thats at about 60% highway driving and 40% street. That also includes me NOT driving crazy ever. dropping the hammer is no good for the milage. Also note that i have a 91 octane tune, so my 19 is probably the same cost as an 87 octane 16 or 17 mpgs. when i pulled this truck off the lot is was averaging only 13.8 mpgs
The intake gave me a big jump in milage and the bb tune gave me another big jump in milage. I recomend both, the muffler was more for sound then performance but i wanted to make sure i had it prior to getting my tune so Justin had it all on the table to work with.

Wow. I'd be pumped to go from 13 to 19 when driving the same streets (hwy/city).
You mentioned the pop sound after letting off the gas (in high RPMs)....I wonder if that is a magnaflow thing.
I had a 99 cobra that had magnapacks on it. I changed them out for the magnaflows and they did the same thing....kinda like a backfire but not as pronounced.

i love my magnaflow... not too loud but sounds good no real drone, but then again its really big and over the axle out the side, puts my kids to sleep : )
Post up a vid.

well i think any straight through design is going to pop at high RPMs... im pretty sure i heard a few sound clips of Corsa's that pop that same way... cambers eliminate the popping however they also restrict airflow
i got probably 2 solid MPG's out of the intake... and then the tune gave me another 3 or so... got a nice agressive 91 octain tune and love the shit out of it... funny thing about the tune, it actually made my muffler drone LESS!
thats not shit either, my girlfriend hated the magnaflow, bitched all the time about it, the DAY i installed my new PCM she got in and commented on how much better the truck sounded and ran...

ok jenna. I need ur help. Bigger I go. More or less noise? More or less drone?

The bigger you go, the less noise you would get. The internals of the muffler is where you get drone.
We are about to test out a theory that we have, that we actually got from the stock intake design. Once we have that fabbed up, we will let you guys know if it works to counter act drone or not.

any news on this design jenna?

No, we have been super busy and probably won't get to this for a while.
I've heard of running a "false resonator" to reduce drone. Simply a 30" or so piece of capped-off pipe just "T"d off of the side of the exhaust before the muffler.
Also, are the Flowmasters really that bad? I freakin love the way they sound and I dislike the tinny/poppy sound with some of the straight through designs. If there's not really much performance increase due to exhaust, as long as the FM's flow as well as stock wouldn't they still be ok? I don't see myself going all the way with LT's and ORY, just want that nice mellow rumbly sound FM's give.
What about two cheap cherry bomb type or bullet type mufflers in a row? Anybody tried that or considered it even?

I ended up with flowmaster 50 series. It drones at 2k rpm, anything above is an incredible tone , below is silence. I actually find the exhaust helping me NOT speed. Which is a great thing for me.

i always enjoyed the FM sound, but its just too loud for me these days, i suppose i am getting old... hahaha... when i get my LTs i might end up doubling up on the magnaflows to cut down on the noise... just a matter of the space needed..... if i have another 16" to work with under the body i will probably end up adding a 14" magnaflow to cut down on the loud

going smaller will make it louder.

My Magnaflow got REALLY loud with the LTs and cam, I switched to Corsa Touring after that.
