Cobalt / G5 Cat-Back Exhaust System Performance 17802111 - Crate Engine Depot

Cobalt / G5 Cat-Back Exhaust System Touring 17802110 - Crate Engine Depot

i have the performance like i said a few posts ago. it sounds goooood

SC cobaltss15

how does it sounds on the turbo ss. I am looking for something different but not loud. Also i heard that the piping is smaller than stock, so what if I just took muffler, and did custom piping? would that work?

it would work u also would need a 3 bolt flange since the exhaust system comes with 2 bolt flange

SC cobaltss15

yay. Would it be louder than the stock ss turbo exhaust? also what if i just did a regular performance exhaust, would it cut performance on it?

why dont u just get a 3in catback from zzp,mpx, or another company it would be cheaper

or for the mean time you can get a 3 inch catless downpipe. thats what my friend has on his 09 ss and it sounds amazinggg with the stock catback.
if i had his car i wouldnt even get a catback because just the downpipe makes it alot louder

SC cobaltss15

okay. I am not going wiht other cat backs because i want something quite, If i go with dp I am going to get a highflow cat, because in virginia they are really strick!

What would be a good header and downpipe to go with the gmpp cat back

Bad-mab header n ZZP catted dp

it deffently does not say size of piping

It's 2.25, the best size for a n/a 2.2 or 2.4. It even an upgrade for the sc because the mandral bends and straight through muffler give it better flow that the stock one of the same size

oo i thought you asked 2 diff things. because i said in the post before it doesnt come with the tip than you said it doesnt say on the site. so i thought you said it doesnt say if the tip was included or not than asked what size it was.

does anyone know if the vibrant header with catless downpipe with the gmpp echaust sounds on my ss/sc. debating on getting it.

pursuitforever

how much guys think gm is going to charge to install it. They already charged way to much for the cat back. And no one posted anything about gains

gm installed my catback for 90 bux.

pursuitforever

So I'm at gm right now qaiting for It to be installed

pursuitforever

Got the catback installed. GM charged me $150 to install it and took an hour and a half. sounds really good but its alot quiter then what i am used to. As for proformance gains i didnt really feel any. There might be a bit in the higher end. But this could be due to the stock downpipe

I got it on my ss/sc and I love the sound. I also gained 2mph in the trap just from it. Before I was running roughly 101.5 traps then I jumped to 103.5's
