So im a 2.2 with a 4-1 shorty header with now a 2.5 zzp catless and a knockoff tsudo exhaust. 2.5 piping basically from the header to the end of the tailpipe.

Im wondering if anyone is running a similar setup that has found a muffler that queits down their exhaust somewhat, i know having a straight through muffler makes it alot louder.

any opinions that dont involve putting a cat on the car or getting a full new exhaust?

I have you exact same setup, and i just fixed my leaks and it sounds good.

Ebay header zzp 2.5 catted downpipe and a tsudo exhaust on a 2.2

I would recommend a LSJ muffler

Maybe you can email ZZP and see if they will sell you just the muffler from their catback. Their chambered muffler is supposed to sound awesome and not be too loud. I think every other muffler people use on cobalts are straight through except for that twin loop that a few people used

im catless not catted. lol i like the sound but ive got some extreme rasp. i may add a second resonator to the setup to get rid of it.

and thats a good idea garrett ill have to ask them.
