im debating if i should get it or not because i know its on sale for 357.00..but thats still a nice chunk of cash....with the tip and shipping it equals out to $434.00. i know it saids 12hpgain ...but just wonder if it s a big difference when i accelerate???any opinoins who have the GMPP?

 

I like it alot...I felt a difference when I first got it and that was before I got stage 2 put on.
Not only do you feel a difference but it sounds good too. Not like a fart can or ricer

 

cause i got a aftermarket muffler and its getting annoying right now..and i dont feel any difference with that..koll i proby purchase it soon

 

yes its noticable.
My interceptor gauge showed an instant 12-16hp increase at the crank.

 

thanks guys ....i like the black rims...how long it take and what kinda paint

 

a full days work.
Duplicolor high performance wheel paint.

 

the gm cat-back exhaust is nice. sound ........its not too loud, but thank god it doesnt sound like a rice burner, the hp gain you can feel plus it looks nice, i would invest in it

 

i just put mine on my 2.4 and i payed about 400+tip60+tax=505$ so i would go for it i got the sport one or whatever i feel a big difference but i also put on the ca header and dp and it sounds sweet as hell and rocks. so just get it.

ryan,

 

you wouldnt really feel the gain as soon as you put the pedal to the metal. You feel it more from top end. I dont have the GMP cat-back but when I put on my catback I felt the difference for sure at the top of gears. Plus you cant beat better gas mileage.

 

damn i cant wait to get mine. WHERES MY TAX RETURN CHECK?!?!

which tip do you guys recommend. straight or angled? ive been thinkin about straight, but the angled looks like it would flow more the with car.

 

I got a angle..I think they're good if you have a light colored car because it helps keep the black exhaust off the body
