Cold air kit
Off-road x-pipe and cat-back exhaust

Thanks, I'm leaning more towards a cat back, air plenum, pullies and cold air. What are the best bang for the buck?

Gears are the best bang for the buck. I'll also say that we've seen as much as 24hp gain from the Xcal2 on bone stock vehicles. Every car is different, but even 15hp from the programmer is nothing to sneeze at!

I'd really like to keep it a highway car. I've got 4.11's in my Torino its not good on the freeway. The Mustang is going to be the vacation car. Are air plenums and such worth the money? Isn't reflashing the computer expensive? thanks
