ok i have a tsuno exhaust set up on my 05 cobalt ss
im looking for someone in or near the tampa area that wants to trade there system for mines willing to even consider trading for a stock system or a nice sounding after market one with cash on my part.

looked under the car today and saw that it has a 3 inch zzp downpipe and a 16 inch resonator gussing it came with the tsuno exhaust because that all thats left after the resonator stupid set up done by the guy before me because the cars stock besides a intake so is this 3 inch downpipe hurting the performance of the car?

 

I wont hurt ur performance just moves the powerband a couple hundred rpm higher. If u come to broward county I have a stock muffler I would sell for $25. But u are better off swapping out the muffler for another aftermarket if it is to loud for u. Search this forum gmpp also same as corsa is the best sounding imho

 

yea i wish i could find a 2.50 inch muffler so that right behind the tire i could just take it off and get rid of the muffler part which is what makes he sound and replace it with another one but im tryiing to find a cheap muffler i dont want to spend 700 or 800
