Good evening everyone. I have just registered with this forum. I hope to learn alot from this forum and get some great advise from the experts. My wife and I just purchased a 2007 Grand Prix GXP....47,000 miles. This is not the 1st grand prix we have own but 1st GXP...so far lovin it!...But I am like many and cannot leave anything stock...So feel free to share the secrets, mods, pros, and cons....Thanks!!

welcome to the forums, however there is not alot of aftermarket support for the 5.3L so i dont know how far you will be able to take your car so just enjoy all the horses the LS4 gives you!

LS4 has little aftermarket support. Boo! Cuz I want a GXP.

Well i guess i will have to do plenty of research and share my findings with all of you lol....GXP is still fairly new....hopfully the aftermarket mod selection increases over time.....But The LS4 still has penty ponies to tide me over for now. I will most likely start with Cold air intake and Cat Back Exhaust....then from there...??
