DescriptionThe whole story▼
Developed alongside MotoGP and Moto2 factory teams, the SC-Project CR-T Slip-On is the uncompromising track weapon for the BMW S1000RR K67 (2019-2020). Saving 1.5 kg over the stock unit and delivering a measured 100 dB of authentic racing howl, this is the silencer that transforms a road-legal superbike into a genuine circuit contender.
Key Features
- Massive weight saving: stock silencer weighs 2.3 kg; the CR-T comes in at just 0.8 kg — a reduction of 1.5 kg at the tail end of the chassis
- Titanium or carbon canister options, both fitted with a titanium outlet grille for authentic pit-lane aesthetics
- T.I.G. orbital welding throughout, with titanium link pipe and titanium end cap for full corrosion resistance under sustained track load
- Solid-billet CNC-machined mounting bushings guarantee a rattle-free, precision fit straight off the standard BMW header
- Verified dyno gains of +1 PS at 11,500 rpm and +0.9 Nm at 10,250 rpm over the OEM system
- Carbon fibre heat shield included — protects the airbox and surrounding bodywork while cutting additional mass
- 24-month official SC-Project warranty — even on full race-specification components
Track Performance
The CR-T series was born from SC-Project's direct involvement at the highest levels of Grand Prix racing. Every design choice — the absence of a dB killer, the titanium internals, the orbital-welded seams — exists solely to liberate the S1000RR's inline-four at the top of its rev range. At 6,750 rpm the system registers 100 dB, a figure that demands use on circuit only. The plug-and-play connection to the standard BMW mid-pipe means fitting time is minimised between sessions, not maximised in the workshop.
Construction Detail
Both the titanium (B33A-50TR) and carbon (B33A-50CR) variants share the same core architecture. The canister shell is either hand-laid carbon or hand-formed titanium; internal baffling is kept deliberately minimal to preserve exhaust flow. The Ø65 mm outlet is finished with a signature titanium grille — an SC-Project race-series hallmark — and the welded bracket mounting system ensures the silencer is positively located under hard acceleration and braking without movement. All fasteners, springs and hardware are included for a complete track-day installation.
Important Notice — Race Use Only
The SC-Project CR-T Slip-On (B33A-50) carries no road homologation and must not be used on public roads. It is designed and sold exclusively for closed-circuit competition use. Responsibility for compliance with applicable sporting regulations rests with the competitor.
Fitment & Compatibility
Designed and verified to fit the BMW S1000RR K67 model years 2019 and 2020. Connects directly to the standard BMW mid-pipe — no additional link pipe purchase required.
