How loud is the GMMG cat-back???
I have a bone stock z28 and i want to put a catback system on it. Is GMMG the way to go. My only concern is that i do not want my exhaust to be overly loud. I have seen videos of the exhaust on ls1sounds but i cannot tell how loud it will be in person. Is the GMMG system consist of a resonater or is it a muffler? thanks

As with most cat-back systems, the catback itself w/out headers will be fine. Once you add LT's, then it will start gettign loud.
My Borla was quiet at idle w/ the stock manifolds. Once I added the LT's, it got loud as h3ll at WOT!
GMMG is one of the top rated Exh systems. If you were to go w/ it, I'm sure you won't regret it....
