The best bang for the buck mods are (roughly in order):

-X pipe with secondary cat delete
-High octane fuel
-ECU software (perhaps matched for the above mods)
-Pulleys
-Titanium cat back exhaust (weight drop and small power bump)
-Increase redline

Some might argue for a high flow air filter but I'm not convinced these actually add power.

With these mods you can count on 30-35 hp gain for about $6k. This car will leave any FD ratio modded stock M3 in the dust.
