Akrapovic Slip-On Line Titanium Silencer BMW S1000RR K46 2017-2018 S-B10SO8-CUBT

Born from Grand Prix racing and shaped by decades of motorsport heritage, the Akrapovic Slip-On Line in full titanium construction is the definitive exhaust upgrade for the BMW S1000RR K46. Every component — from the silencer shell and end cap to the internal structure — is crafted entirely from titanium, delivering a combination of weight savings, power gains and a race-bred exhaust note that no stock unit can match.

Key Features

• Dramatic weight reduction of 3.2 kg over the standard exhaust (stock: 4.3 kg, Akrapovic: 1.2 kg), transforming the S1000RR's weight distribution and agility
• Measurable power increase of 2.7 hp, raising peak output to 192.7 hp at 13,400 RPM compared to 191.2 hp stock
• Torque gain of 2.1 Nm at 8,500 RPM for a noticeably stronger mid-range drive out of slow corners
• Sound level raised by 4.2 dB to 103.2 dB at 6,750 RPM — a deep, purposeful GP exhaust note rather than artificial noise
• GP 1 silencer design with full titanium shell, end cap and internals, including the carbon heat shield supplied in the box
• Direct fit to the original BMW header — no additional modifications required for installation

Design, Finish and Heritage

The GP 1 silencer profile is not a cosmetic afterthought — it is the same form language Akrapovic developed for World Superbike and MotoGP programmes. The natural titanium finish ages with character, developing a distinctive heat-blued patina that tells the story of every session on circuit. Unlike painted or stainless alternatives, the bare titanium surface is part of the product's identity, and it pairs visually with the S1000RR's angular bodywork in a way that aftermarket canisters rarely achieve.

Every metallic part inside and outside the silencer body — the tube work, the internal baffles, the end cap — is machined or formed from titanium. This is not a titanium-wrapped stainless core; it is titanium throughout, which is why the weight figure of 1.2 kg is achievable without compromising structural integrity at racing temperatures.

Performance on Track

The 2.7 hp and 2.1 Nm improvements documented by Akrapovic are measured at the wheel on a back-to-back dyno run with the standard header in place — the same conditions a privateer racer would experience. At 13,400 RPM the gains sharpen throttle response in the upper rev range, while the torque uplift at 8,500 RPM translates to quicker drive exiting medium-speed corners. For track-day riders and club racers running the BMW S1000RR K46, the combination of reduced unsprung and reciprocating mass plus the modest power increase makes this one of the most cost-effective single modifications available.

Fitment and Compatibility

This silencer is designed specifically for the BMW S1000RR K46, model years 2017 and 2018. It connects directly to the standard OEM header pipe without requiring modification to the stock exhaust manifold. Part number S-B10SO8-CUBT. This product carries no road homologation and is intended exclusively for closed-circuit racing and track use.
