what are the best mod's for 2002 gt im thinking about headers catback system and cold air system and underdrive what hp gains would this give me and are these all good mod's for the buck.

 

That is really a loaded question and there will be many different responses, but I will try to help:

Headers: There are three styles. long, medium and short. The long ones (LT's) will produce the most hp, but are expensive and a real pain in the *** to install. Expect about 0 - 20 hp depending on which ones you go with. This si not a good mod at all for a beginner as you also may need a dyno tune when you are done. Headers tend to lean out your a/f.

Catback: Great mod! Worth the money just in sound alone. Lots of options available and expect anywhere from 0 - 10 hp tops depending on your choice.

Mid Pipe: I recommend either an after-market H pipe or an X pipe. You need to be careful what you select depending on your catback choice. A good mid pipe will get you 10 - 15 hp.

UDP's - Great idea. Cheap and an easy 8 hp. You can install yourself, or pay a mechanic. My ford dealer charged me $50 which was well worth the money.

CAI: I have one, but I think they are not worth the money. Unless you want some bling under the hood or a blower, leave it stock.


There are others, but I just discussed the ones you mentioned.

 

blower. period

 

Dom, you are such a wise guy! lol.

 

well. haha. headers 400 bucks, mid pipe 200, catback 400. cold air 150, udp 170, thats like 1500 bucks when u include shipping. and 2000 if installation costs for headers are necessary. so get a used blower kit for a tad more and get a much better turn around wise guys
