Damn I was going to do that after lab. Why you gotta beat me to the punch. Carry on 
Go talk to the local dealer(s). Often they will allow certain things go by. The local Mitsubishi dealer doesn't care about a exhaust, intake, etc. Can even let a tune slide if you have a strong relationship; however, the dealer in the next town is so strict that if they even see your car with an intake or exhaust they will void the warranty then and there. lol. Asking is smart.
