Hey everyone. I have ordered a new 05 Mustang and was curious what everyone though the first mods should be to the car. I would like to do as much as possible, without voiding the warranty. Anybody tried reflashing the computer? Any other ideas?

Well get it sounding tuff with an exhaust system.

Any suggestions on which exhaust sounds best on the 05? I had Flowmasters on my 98, and I have Flowmasters on my 01.

How much HP gain can I expect? I have read that the exhaust on the 05 is much better than the years past.

i read in some magazine that hey added a magnapack catback and gained zero horsepower. it does give you a better sound, but those 400-500 dollars could be spent on something else.
