I have an 04 ex and it runs great. commuting i'd get 370 to the tank but recently since I've been in city its been much less 260-300. my car personally other then the not too bad sounding muffler and the 17" rims (now have 03 SI rims on it) the previous owner had on there the car runs great and has had no problems so far. I would recommend one for daily use, not really to mod. hope that helps.
