Exhaust Systems for the 2019-Up BMW G20 3-Series (330i, 330e and M340i): 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 3-Series fitment.
M Sport and standard cars use different front and rear bumpers, so lips and diffusers are sold by bumper. The 2023 LCI changed the headlights, grille and lower bumper inserts, so some front pieces are 2019-22 or 2023-Up. Exhaust systems fit by engine, not by trim. This page covers 330i, 330e, M340i and M Sport; each listing states the exact trims and model years it fits.
Materials run T304 stainless steel. 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.
