Remus G80 M3 / G82 M4 Racing Axle-Back Exhaust Titanium | 21-27

Remus part 081021 1401 + 081021 1510TI + 0048 70TI is an axle-back exhaust developed for the BMW M3 (G80), BMW M4 (G82) and BMW M4 Convertible (G83). It fits the 2021-2027 model years sold in the US. For anyone searching for a g80 m3 titanium exhaust, it is a direct-fit Remus option. Remus has built exhausts in Austria since 1990 and develops each system for a specific vehicle, so the fit is direct and no cutting or welding is needed.

What It Does

It is a rear-section upgrade: the stock rear muffler comes off and the Remus silencer bolts on in its place, so the change is mostly to the sound and the look of the rear end. Remus lists pipe diameters of 100 mm for this part.

Sound and Character

Remus tunes its exhausts for a sporty but refined sound: noticeably fuller than stock, without an intrusive drone at cruising speed.

Vehicle Coverage

In the US market it fits the 2021-2027 BMW M3 (chassis G80) with the 3.0L Twin-Turbo I6 (S58) engine; the 2021-2027 BMW M4 (chassis G82) with the 3.0L Twin-Turbo I6 (S58) engine; the 2022-2027 BMW M4 Convertible (chassis G83) with the 3.0L Twin-Turbo I6 (S58) engine. Model years follow the US market, not the European production dates Remus publishes.
