I'm ready for an exaust.
can anyone tell me the difference between 4" and 5". what will be the advantages and dis-advantage.

Maybe recomend me the lower price ones.

thanks,
Ace

4" for efficiency, 5" for vanity. The aluminized systems are the cheapest and probably fine for California. If you're going to go to the trouble, though, a stainless systems seems the way to go. Lots of opinions here on which is best.

I currently have 4" exhaust on my 2004 & having trouble with resonating sound
at 1500 to 2,000 rpm's. It's a deafoning roar that really gets on my nerves. I
called Corsa Exhaust Systems & they give me allot of good info., they warranty
their exhausts systems for the life of the vehicle with no resonating & say they
are quieter than stock exhaust, so I ordered the turbo back system, will let ya'll
know the results when we get it installed.They are expensive!

I was looking at the proflow / flopro turbo back system for $260. do you think it's a good exhaust?

I installed a 5" aluminized on my 2001 and don't have any problem with the noise in the cab(windows up) It is a little louder but I like the deeper sound. It has made a difference in performance and I usally average 19.5 to 21.5 mpg empty even going to Klamath Falls Oregon from Oroville Ca. and back.
And Hey! if it's vanity then I'm glad I'm vain.

I feel a movement of this thread comming on...;)

But anyways, My MBRP 4" 409 stainless wasn't that much and was well worth the money. Just don't go too cheap. my friend put a 3" pipe where the stock muffler was. It sounds like SCensored That might be just because of the size of the pipe and the Tip tho

Well I just installed my 4" exhaust turbo back with a 5" chrome tip.
and wow it sounds great. and the milleage that shows up is about 20-23 on the freeway.
I'm thinking of going straight pipe without the muffler to make it a little louder.
what do you guys think?
Where can I get a 4" straightpipe?
