OK, I've had my M3 for about 3 months now, and its great, finally getting used to it, and all. Its not that I don't like the engine's high pitched growl, I just think it could benefit from a deeper sound.
The Dinan exhaust is an option, but then I have to switch to the Dinan's warranty. Anyone have any experience with Dinan's warranties? Also, does anyone have the Dinan exhaust, becuase ?
