Looking for exhaust systems for your BMW M3? That's all that's here, so nothing below is going to waste your time. Tell us the year and the trim and you'll see only what fits yours, back to 2001. It comes down to the year, engine, drivetrain and body, which is what the fit check is looking at.
You're here for the sound, so let's start there. An axle back swaps the muffler and tips, goes on in an hour and changes tone more than volume. A cat back takes everything behind the converter, mid pipe and resonator included, so it's louder, lighter and a bigger job. Both stay legal everywhere because the catalyst doesn't move. Downpipes replace it and they're off road only.
