The only problems with that are that it stores "exhaust valve" error codes in the ECU until the tech clears them, and for sedan owners, its really not that much louder. I could barely tell a difference when I did it to mine. I think a lot of people get a placebo effect in they hear what they want to hear from it. It definitely doesnt give you any more power, quicker throttle response, or louder turbos.
