I'd just page through the performace mod Forum and check out stuff on Exhaust/ECU. I wouldn't expect a MPG gain at all. Some people do get a slight gain, some people get a slight drop.

NaturalMystic79 Posted December 9, 2004 Report Share Posted December 9, 2004 I wouldn't expect a huge change in MPG w/ just an exhaust. I got maybe 1mpg better with exhaust. Link to comment Share on other sites More sharing options...
