So, anywho...after installing it was a lot quieter than i expected although the gains were very evident. More low-end and mid range, but some top end did suffer. Very easy install, maybe a total of 30 mins by myself on a lift at work. But, the only bad thing about the whole deal is tip i got, it was the straight cut design, its very goofy looking and bigger than i expected. I didnt like it at all, and i plan to change it out. Im gonna post up pics here sometime this week of the final product. I recommend this exhaust to anyone who wants decent performance but yet still has a decent tone.

 

good news! i thought about getting the gmpp but im not sure if i would rather get a custom job done. where in texas are you?

 

I got the gm catback also, I love the sound it makes!

 

im guessing by your picture that you have a pontiac. i think they should make the userbars for the pontiacs as well with the color options

 

yeah! I have the pontiac, a guy a my dealership has the cobalt, he spent 60 bucks and switched out the cobalt grill and put on the pontiac eyes.

 

wait, you went from stock to the GMPP one and noticed a loss in high rpms?

 

can we get a sound clip, assuming you are manual

 

i'm wondering the same thing as elmstreet... where in texas are you from? i'm from the Weatherford area if anybody has a clue where that is! well... can't wait to hear the clip and i'm thinking about getting the same exhaust!

 

im in arlington

 

yea im also wonderin how u had a loss at high rpms. that doesnt make sense one bit

 

I installed a GMPP touring system w/extruded manifold for a customer of mine a few weeks ago. I can say this system sounds GREAT; nice deep tone at idle and heavy load. Not too loud nor ricey at all, would like to compare it face to face with the Sport version.
I personally witnessed an increase in power the upper RPM range, the same effect as with my own car when I installed my CAI. I do have the benifit of comparision with stock vehicles that are on my lot. IMO, the exhaust looks great, sounds great, adds some gain in perf. (I do feel the muffler IS the biggest restriction, next to the manifold), but wish the system was 2.5in. just for piece of mind and future mods.

 

The reason why your confused is because i had a custom 2.5in exhaust with no muffler, just a 30in resonator to keep the loudness down, so you can see where i lost some top end going to a lower diameter pipe, but this one is mandrel bent, the other custom was crush bent, but all in all a very nice system. And im from houston,texas to the guy that asked...

 

Yes i am manual, and ill do my best to get a vid, right now i do not have a tip because the one i ordered with the catback system was awful, to big and goofy looking and didnt quite fit right, ill get a vid up as soon as a better tip is on...

 

ah ok that would make sense then, thanks for clearing that up

 

where can i get this exhaust?
