headers are headers are headers, depends if you like paying for name brands or not, get them off ebay and be happy!

They are both good lol, your just paying for labels when you shell out the big bucks.

No and not putting one on, I am not shelling out 600$+ for one that I could drop into the engine and make much more bang for my buck. You can get the exhaust if you want but it isn't going to help at all but make your car louder and possibly sound worse

stock exhaust is the way to go

exactly what is in my signature

I have nothing on my car as of yet. I am ordering it all and putting it in the warehouse until I can find a weekend/week that I can install it all at once.

haha no not at all

No its just a body style lol, coupes look faster but aren't. I like sedans because people won't think it's fast and won't mess anything up getting in the back seat.

The pace-car replicas had special Medium Gulf Blue Metallic paint, unique "Sparkle Silver" 16-inch torque star aluminum wheels, custom decaling, a plaque notating the specific model number and custom door panels.

not any performance additions

x2 he got it right

Here is everything in a nutshell and I'm tired of reading this thread

1) Take off the 3.4" Pulley
2) Install a 180* T-Stat, if not done already
3) Install colder plugs if not done already
4) Get a Set of headers (they are what they are...you pay more for better fitment and coating materials...and yes a name brand.)
5) Get a PCM. ZZP = EPIC FAIL, do not go that route. Whoever does their tuning sucks ass. Go with a DHP, or Overkill. You can get a DHP from PFYC.com or 3800performance
6) Flowmasters = awesome. As long as you keep the resonator they are fine. No performance increases but the stock mufflers are the best muffs perf. wise anywhere.
7) SLP GTX is the Grand Prix that had a Ram Air Hood, 3.5" Pulley, SLP Catback, and Intake from the factory.

Hope this clears it all up.
