Been looking for after market parts for my ride. I would like to increase HP and Torque. All I seem to find are truck parts that wont fit my engine compartment. I just want to go alot faster.:th_nanana: Need more horses to keep up with the G8GT 362hp dont like to be beaten. If anyone knows where to order after market parts for this car please let me know. THANKS
 


IMO Pontiac Screwed up with that Model and should have made the GXP rear wheel drive. That way you could mod it alot easier. Good luck finding mods. Sorry I can't be of any help.
 


Rockers, exhaust, downpipe, cai, tune, tbs, ported tb/intake, turbo and trans with 3.29 gearing ($$$), springs, stb...etc
 


i too have an 08 gxp. anybody had problems yet w/ the middle dash speaker. its makin a buzzing noise. im guessin to a lotta people thats old news. i read in other places that people have made the replacements, but w/ the same speaker, and it too buzzes as well. any ideas or information on what i could or should do. its under a warranty for quite a while, and im just wonderin what to do. i love listening to tunes, and theres no way im going to put up w/ this for long??? aim = bumrock41. thanks.
 
go to pfyc.com,click on grand prix, they have a sweet turbo kit out for the gxp,comes with everything needed,it is a small but powerfull unit ck it out
 
Hey I have a 2006 gxp and the same exact thing was happening to my speaker. on mine it was the right door that was buzzing. i took it in and they replaced the speaker and it did nothing. they need to replace the head unit and that fixes the problem.
 


hey thanks for lettin me know man. im gonna take it to my local pontiac dealer and let them know. itll piss me off if i take it in and it does absolutely nothing. they should fix it all or nothing. thanks again.
 
I bought mine in October and have not heard the buzzing noise yet. How long did you have yours before it started?
