I have a 2000 grand prix GT i just got recently and i want to start modding it. i basically have no clue what is what so... if anyone could help, thanks ahead

Cold air intake,exhaust,pcm

First, you will want to open up the intake with a K&N cone-style filter.

You can either;
a) Buy a Cold-Air Intake from www.pfyc.com ($200)
or
b) make one yourself using one of these two guides (~$45-$55).

Then you will probably want to move to your exhaust.

Performance wise, you will be looking at 2.5" downpipes with U-bend deletes and high flow catalytic converters from www.zzperformance.com along with possibly a ported front and/or rear exhaust manifold. (~$150 - ~450 depending on how much you want).

Sound wise, I would suggest a pair of Flowmaster Super or Original 40 mufflers (~$70)and a set of either dual or big bore tips (~$25-$75).

If you do both the exhaust and intake, you are going to need a reprogrammed PCM to help the car use the new increased flow (~$100 with a $100 core charge). You can buy a DHP 1.0 PCM from www.pfyc.com or a ZZP PCM from www.zzperformance. I'd suggest the ZZP PCM as their service and quality are unsurpassed in my book.

After that, you get into things that are going to require more skill and $$$.

if you get in a bolt in dp you wont have to do a u bend delete you only do if get a u bend delete if you run a shorty downpipe

i have about $300 to spare right now so i guess i'll get a cold air intake... uh i may be wrong but its either a wizaired cold induction system or a K&N Aircharger... looks like the K&N is more expensive but which is better?

alot of people buy eather the slp cold air system or the Wizaired Cold Air Induction System. I think that with k&n you pay for alot of the name ... yes they have good stuff but you also pay for the name... buy eather the slp or wizaired cold air kit then you can have some extra left over to buy some other stuff. have you done anything to your exhaust yet??

no i haven't yet.... uh this may be the dumbest thing anyone has ever said but grand prix's are supposed to have 2 exhaust pipes right? cuz mine only has one but it has a place where another one should be... i don't know exactly whats going on with it though

It is quit possible someone before you got rid of the other. You need to check and see if that is the case or you lost a exhaust tip or even the muffler.

are you shure its a gt and not an se?

ya its a GT... i looked up under it and it is just the tip of it... guess i'll be buying new ones...
