Okay, so I just purchased a 2102 Evo MR, service techs told me there is a laundry list of upgrades that i can't do because Mitsubishi doesn't "condone" racing, and an Evo should already be good enough. I already have a catback exhaust system waiting to put on because the tech said that if i put it on or have it put on that if the cat goes bad it will not be covered by warranty...but how can that be if it is behind the cat? Anybody know? Already had to trade out a k&n intake for an AEM dry-flow since they said it would void the MAF sensor if oil from the k&n got onto it. Anyway if anybody has an answer about the exhaust please let me know, i would like to have it put on as soon as possible. Thanks. And if anybody knows where i can get a rubber key fob cover/protector that would be great too, since i can't seem to find one ANYWHERE.
