Okay, so I just finished installing my ZZP header and down pipe. It sounds like absolute ****! I beleive this is because I am still running the stock muffler.
Which mufflers sound good on this setup?
Thanks!

 

i have the zzp shorty header and dp and i returned back to a stock cat back... i dont have a problem with the way it sounds

 

I went catless, no resonator or nething

 

Welllllllll There's your problem.



You might want to get a resonator to fix the issue.

 

thats what catless is supossed to sound like lol

 

Well the dudes at the shop did it, and now it just sounds awful.. fuuccckk

 

get a custom pipe setup with an hks hi power muffler. nice deep tone

 

Well I did get a custom setup, where the resonator was they put straight 2.5 through to the muffler..
sorry not to the muffler but to the other piping

 

is it like a leaking/ticking noise?

 

no its like a bumble bee rice noise..

Definitely get a resonator. I went with magnaflow and I love the sound. I think they make a 2.5" as well as a 3". If you're on the stock system get the 2.5", eliminate the restriction over the hump and get a high flow muffler and you should be ready to go.

 

the muffler wont do anything buy make it louder and more free flow....get a resonater for sure.....try that with the stock muffler...that might sound good...then get the muffler

 

well thats why its sounding like that. you took out the cat AND the resonator

 

Well how does the header/catless downpipe sound on stock catback and resonator?

 

well ****, the dude literally cut out the resonator.. I didn't really give him permission, I told him I wanted to go CATLESS.. I still have it sitting in my trunk, can I get it re-welded back in?

 

Just get an actual cat back. Like Magnaflow, GMPP, Corsa, etc. It will sounds a lot better with that. It sounds like **** because you went catless and you cut the resonator off.

 

well I have like $200 MAX to spend on my car in the next month so thats a bit of a ****** let down.

Okay, well I just got off the phone with them. The guy offered to put in a "twister" Im not to certain what it is but he said it is similar to a resonator but smaller.. Any input?

 

Get an actual resonator, it's what makes the exhaust quieter and less raspiness, exactly what you need.

 

I'm going to say you have a gasket leak...I have a vibrant h/dp to the factory cat back sounds pretty good when it's not leaking.

Just read this...yeah it sounds like **** because you deleted the cat. If you have the factory cat back you still have the factory resonator...nothing really is going to make it sound not raspy or dump truckesque.

You deleted the resonator as well? I hope you're not planning on doing any highway driving it will destroy you!

 

Okay, so when I go in tomorrow I should say, I don't want your "twister" put my stock resonator back in!

 

flo pro 3' v-force muffler, i got it on my car and it sounds deep

my resonator is also gutted.

 

another reason why srt is better then cobalt...put any bigger exhaust then factory, with cats, no cats, nothing, and it will still sound beastly....


but yea, put a resonator on. zzp has a whisper resonator that acctually works wonders.

 

Get a whisper resonator

 

ive heard those whipser ones restrict flow pretty good.
