Whether it be mufflers or catbacks.

 

Pacesetter headers, Catco cat, Dynomax catback

 

dynomax cat-back, dynomax high-flow cat

 

3inch no cat and Super Traps

 

Stock Manifolds, AP mandrel-bent Y-pipe, Catco hi-flow catalytic convertor, Dynomax Super Turbo cat-back.

[edit] Haha, wow, Dynomax is definately the home team, huh?

 

3" Flowmaster mandrel catback... And 3" mandrel bent before that.

 

Stock manifolds, no cat, stock pipes, 3 mufflers

 

tubular exhaust manifolds, no y-pipe or no cat (for now) and dynomax catbak.

 

stock manifolds, stock y-pipe in rough shape, dynomax cat, cheapo crimp-bent I-pipe, and cheapo muffler/tail pipes...
for now...

edit: I forgot to mention that I had to rip the hanger off the I-pipe and now it has a noisy, backfiring, gaping hole. They could not possibly weld the hanger onto the pipe in such as way as to create more stress... are they stupid?

edit #2: I've still never heard of anyone with a V6 who used the dynomax Ultra Flo system. If anyone has used it I'd like to hear if it performs well/sounds good.

 

Plus the tips look bad *** on that Ultra Flow... a long time ago (over 10 years?) I heard the Ultra Flow setup on a GTA... it sounded damn sweet. I never heard a GTA sound that good before.

 

Stock manifolds, y pipe and I pipe. Catco high flow cat and Dynomax Super Turbo muffler.

 

Whats an "I" pipe?

 

The pipe between the cat and the muffler. Intermediate pipe, hence "I" pipe.

 

Yes, it is not shaped like an 'I' like an H-pipe is shaped like an 'H' (in fact they'd be the same thing!). But that's what I thought initially.

 

Hey! Who's got the MagnaFlow? How's it sound? Which model??

This is a website of a guy i kno with the ultra-flo exhaust system on his car. This link will take u right to his exhaust clip.

 

I'm glad someone found someone that actually tried the Ultra Flo. It doesn't sound much different from the Super Turbo and I think it may be too open. Like Dean says, the two 2.5 exit pipes even open it up a little too much.

 

Dynomax catback, pacesetter headers.

 

Flomaster American Thunder series 3" Catback #17234. USes the 80 series muffler. Very low tone, but 3" is too big for a V6.

 

I have to disagree to that

 

right now I have stock exaust, but after I get a base line on the car at the track next weekend I will install my dynomax ultra flow!

 

Well i had 2.25 all the way to an 80 series and that sounded awesome. But i had a leak and the whole install was real shotty, so i opted for the 3" catback. Its lower, and louder. And despite what most people say, its sounds better 3000rpms and up then my first setup. But lower than that there is too much reverberation. You hear more of a vibrating rumble than the up and down of the engine, ya know? Hard to explain. But spent too much money on it now to change it back. However, there was a significant power increase. Probably because the old setup was so dented and not mandrel bent.

 

i disagree too!
