Thanks guys
So I didn't have to use a t/b. I sow that all of you said that the tuner is more better. Ok so wich one is better ? Hypertech , Diablo sport or Scat ?
Actullay I used the diablo on a 2001 Mustang GT auto trans it wasn't good for me ( as they said that it's give u 20 - 25 HP.
No body answer me about the Long Tube Hooker headers with it's X pipe is't nice ?? I will use the stock cat back.

if you have an auto get the xcal2(SCT), if you have a stick get a predator. thats pretty much the general rule right now. the xcal2 can be used for 5speed cars but most seem to use the predator so you will most likely get more tunes for the predator.

as far as using an x-pipe thats really your preference. there is almost no power gains from replacing anything on the exhaust with the exception of putting L/T headers on. L/T's are worth about 15-20hp. the rest x/h pipes and axle backs are just for sound. find one you like. you can't go wrong on those!!

Good mods, you must get a tune for them though or your car will not run right.

as far as the headers go everything is good except i feel something in the steering. i checked to make sure it's all tight and seems okay. i think the headers are rubbing against the steering shaft. but only on a hard right turn. this must be why some others have gone to the steeda motor mounts. i know the stock ones are pretty spongey. i'll change them when i have the k/member dropped.
