terryk2003 Posted March 16, 2010 Report Share Posted March 16, 2010 So, my exhaust keeps getting louder and louder. Its too the point now where i cant stand to drive my car and it needs fixed before i get pulled over. I crawled under the car after work last night and upon a first inspection it appears that the back of the resonator is rusted off...soo, i'm thinking about buying a catback system instead of trying to splice mine back together. I'm debating between the GMPP System or the SLP PowerFlow system. Summit has both and i can go pick them up to avoid crazy shipping costs. The SLP has no resonator where the GMPP system does...i'm thinking i'm gonna want the resonator to quiet it down a bit more and reduce interior noise, but if i get the SLP system i dont wanna have to hack it apart to put one in. Basically, what i'm asking is for opinions between the two...i can't seem to find any sound clips of the GMPP kit which would really make my decision easier...if anyone has any clips that would help alot, otherwise, if you've heard them both i'd like opinions on which sounds better. Thanks! EDIT: Sound Clips SLP: GMPP: Quote Link to comment Share on other sites More sharing options...
KingVee Posted March 16, 2010 Report Share Posted March 16, 2010 I'd personally go with the GMPP, but it's up to you as far as the money is involved. GMPP kit is expensive as hell. Quote Link to comment Share on other sites More sharing options...

Should of taken him up on that... His GTP is the best sounding 3800 exhaust I have ever heard! Only one I can honestly say I have liked the sound of.

Jamie I actually might hang on to it.....The guy I was supposed to trade that for his GMPP catback kinda backed down and wnted to keep it.....I might just put in a 3'' magnaflow high flow CAT into the DP to quiet it down a tad...(or at least try to get rid of the drone from around town driving....its frikn LOUD) Quote Link to comment Share on other sites More sharing options...
CSI_MuNkY Posted March 19, 2010 Report Share Posted March 19, 2010 Mine is too loud too! I will be looking to get rid of my magnaflow mufflers, go to something that is baffled and then put an electric cut out ahead of the cat. Jamie Quote Link to comment Share on other sites More sharing options...
terryk2003 Posted March 19, 2010 Author Report Share Posted March 19, 2010 SLP's fit and installation instructions are a fucking joke! I have to move a mount (which it doesn't explain which one) and then hopefully shit will start to line up. Right now it doesn't even look close! I'm not impressed at all...so much for being a "bolt on" system. Quote Link to comment Share on other sites More sharing options...
