i was looking at some other posts about this. most everyone suggested cai, exhaust, gears, etc. i just recently bought an '02 auto mustang. i have a price range of 500-1000 or so. I was just curious to get some other opinions on what would be best for increasing HP. Any ideas and comments would be helpful.
thanks.

 

4.10 gears + limited slip diff 600 bucks the go to a exhaust have a system made and installed 400-500 buck there is lots of brands to choose from.

 

Yep..basically what cheddar said..

I've got a 02 auto..same route as i'm going.. good luck with it all!
