Just got done installing my new GMPP exhaust manifold this weekend and was pleasantly surprised. I really wasnt expecting to feel a difference just from the manifold but i must say i feel like the car drives much better now. Probably due to the combo of the intake and manifold the car feels much smoother to drive and has a little better sound to it.

Just gettin some info out for the others that are installing this i am satisfied and would do it again.

 

Awesome... I'm going to order mine this week.

 

Good stuff. Yep more air in + more air out = POWER! Gotta love it! Congrats.

 

Cool. Im thinking of doing the same thing but Im waiting till I get some other things done first.

Later

 

sounds good man, im actually gonna get it soon. Call me a *****, but ive seen way to many threads about poor fitting headers. I really want the cti, but its too expensive for me.

 

the thing actually works, i was surpirsed, but right after the intall i definatley felt a difference in acceleration.

 

Yeah I don't hear good things about headers for our cars. I do know this XTC header is kick ass though. I had no fitment issues and no leaks. The butt dyno says it's working lovely.
