The Akrapovic GP Slip-On is a bolt-on muffler covering BMW's 2020-2025 S1000RR, M1000RR, S1000R and M1000R.
The GP designation refers to the canister's shape and internal layout — short, aggressively tapered and derived from what Akrapovič runs on their race bikes, rather than a road muffler with a sportier end cap fitted.
Those four machines share the ShiftCam inline four and its exhaust routing, which is why one muffler covers the faired superbikes and the nakeds alike. On the S1000R and M1000R in particular, where the canister is fully exposed, the short GP shape changes the bike's proportions noticeably.
Fits the 2020-2025 BMW S1000RR, M1000RR, S1000R and M1000R. BMW has redesigned the S1000RR more than once — the 2017-2019 and 2010-2016 machines take different mufflers, both of which we stock. Check your model year before ordering.
Check your local sound and emissions requirements before fitting.
