Help on what to do in tuning up my mustang
 

I have A 1996 Mustang I just bought it has 78400 miles on it. I was woundering what can I do to make it perform better. There dosm't seem to be anything wrong with it but I just got it. I am going to install a cold air intake, on thursday and duel exhaust in two weeks it's a v6 3.8 engine. Any Tips will be much appreciated :)

put a 355 gear in it. that'll wake it up some and it won't hurt your gas mileage alot.
