Exhaust Systems for the 2015-18 BMW F80 M3 sedan (including Competition and CS): axle-back mufflers, full cat-back systems, downpipes and front pipes, mid-pipes, valve simulators and muffler deletes in T304 stainless, with chrome, black and carbon tip options. Exhaust is the one upgrade you hear every single drive. Everything on this page is confirmed for M3 fitment.
All F80 M3s share one body and bumper design; the 2016 LCI only changed the headlights and tail lights. The F82 M4 shares the front end, so most F80 front pieces also fit the M4, and S55 exhaust systems fit both cars. This page covers M3, M3 Competition and M3 CS; each listing states the exact trims and model years it fits.
Materials run T304 stainless steel with carbon fiber tip options. Systems are mandrel-bent and TIG-welded; each listing states resonated or non-resonated and the tip finish.
Frequently asked
Will I get drone at highway speed? Resonated systems here are tuned to stay quiet at cruise and open up under throttle. Non-resonated and muffler-delete options are louder throughout and say so.
Do I need a tune? Axle-back and cat-back systems are bolt-on with no tune required. Downpipes and header changes are the only ones that may need one — each listing states it.
