I've heard only good things about the gmpp performance exhaust for our 2.4's wanted to get other people's opinion's on it. i want a mean sound while adding horsepower. Is the GMPP performance exhaust the right choice to go with?

 

Search man, theres tons of info on this.

In short, gmpp the quieter of the exhaust choices and gmpp parts dont provide the best gain compared to what they cost.

I'm bias though, I've only ever thrown magnaflow on my cobalts. Its got a deep growl at 2k but at 6k its loud and mean as hell.

 

I have the GMPP. I wouldn't switch it for anything else.

 

They are good exhaust.. not very loud and other aftermarket exhaust do yeld more horsepower.. The GMPP Cat- Back does have a nice tone.. I am friends with a guy that runs a performance and he manderl bent a custom Cat-Back for $300 including a Apexi Stainless muffler.

 

gm touring sounds amazing.. have it on mine

 

I have GMPP as my catback and I love the sound, it's not too loud but still sounds amazing. I get compliments on it constantly.

 

I have GMPP on mine, does exactly what I would want it to do, and it sounds awesome to me.
