Gmpp exhausts?
ok im looking into a new exhaust for my 07 ss/sc and im wanting to stay with the warranty so i looked at gmpp.. but they have 2? what is the diffrence between performance and touring.. ive listened to sound clips online and they sound almost exactly the same and i really have no idea what the diffrence is and if there are any pros and cons to either system.. any help would be apreciated thanks

If you didn't know this already, even with an exhaust you're still restricted. At the 02 sensor on the SS/SC stock DPs, it pinches to 2 inches. I've decided against an exhaust until I can get the DP replaced or just cut out that part of the pipe and swap with a 2.5 pipe (my brother works at an exhaust shop, so it's free for me =))
But from what I hear, they give the same gains. But the Touring definitely sounds better.

don't listen to these morons about the sport, it doesn't sound "vicious" or good in any way, it sounds like a fukking fart can on a 200hp car.
everyone here also told me the magnaflow sounded good, it sounds like ass and they also told me the hahn sounded good, it also sounded like complete ass.
I ran the gmpp for over a year and it sounds the best out of any of the 4 exhausts i've owned and from ANY cobalt i have seen in person. don't pay attention to youtube or other videos because you can't hear the crappiness through the video

its the cheapest made and sounding exhaust out there next to the megan imo. Its 2.25 was too small for what I needed, and the fact they rust out pretty quick was enough to for me to take a pass.
However all exhausts on a 4cyl (with the exception of the boxer) are going to sound farty just by the nature of it being a small displacement engine imo. Some are just worse than others. I mean I had my exhaust for the added flow and performance.

We had a guy dyno a full GMP exhaust on his LSJ with a 2.7 pulley. Not sure if it was touring or performance. He said the difference was about 8-9whp. He is on this forum and goes by Doc. He's since sold his car and has a Tacoma, but still logs in every now and then.
I haven't checked to see what the oe tip is. Do you know off the top of your head?

^ My car w/ GMP PERFORMANCE exhaust..
Idk where these people are coming up with saying it sounds like a fart can...
As far as I'm concerned.. The touring is the same sound just more quiet.

loud does not equal a nice sound.
they do not rust fast because they are stainless steel
for chris, yes your car sounds just like a fart can, except not as loud as some. you can hear it clearly through the horrible music in your video.

Ok so from everyones input I can see that both exhausts are basically exactly the same except that performance is louder and touring is a bit quieter.. And seeing as im trying to keep my car as a sleeper I believe ima go with the touring.. But I've heard that the resonators are known to hang low and scrape easily.. anyone ever have any problemss with this?

the resonators do not hang and scrape, they're not very big at all
you may run into issues if you like in the same area that duke of hazard was filmed, but other than that, you'll be fine
