Help build my car! I need some help, opinions, ideas, and input on my 2005 Grand Prix GXP 5.3 ls4 DOD. I want to do some decent modifcation to the car, not a ton but enough to gain some power and torque.
The obvious stuff going to be done is, Cold Air Intake, 180* tstat, and 3" downpipe w/ highflow cat and magnaflow catback.
I want some information on options for doing aftermarket Throttle Body, Headers, Injectors, and some basic stuff you would reccomend. Also really interested in doing a bit bigger Cam while maintaing my DOD, who makes a cam and what kind of power gain should I seem to get out of it?
I am very serious about doing some work here soon. Let me know what you would reccomend doing and what it takes to do some of the work. Recently bought the car and want to start getting some more power at the wheels.

Well, all I have to add is this:
Start with the basics and work your way up. Don't bite off more than you can chew, do your research, and don't forget the little things.
If you have any specific questions, feel free to ask. People here are a vast pool of knowledge waiting to be tapped.

There isnt much of an aftermarket throttle bodys. If any thing we have been leaning to a port job, or using a larger one from GM.. Big deal is the restriction in our intake. the inlet is a D shape in order to make clearance for the DOD oil preasure sensor. Compared with the standard O shapped LSX intakes. Dont waste money on an after market MAF. and there was talk of using TB spacers for a while.
