i recently put a universal exhaust on my mz3 and was wondering whats gonna happen to my warrenty and if i take my car to a mazda dealership what they are gonna say... is there a paper that i have to sign or do they record this on a computer that states that my warrenty is gone? reason i am asking this is because i have to bring the car back to them and have them program my remote cuz they didnt give it to me when i bought the car. thanks a lot guys...
