Termignoni GP-Classic Slip-On Kit for BMW S1000RR K67 (2019-2020)

Built without compromise for the track, the Termignoni GP-Classic slip-on kit transforms the BMW S1000RR K67 into a sharper, freer-breathing race machine. The combination of a carbon fibre and stainless steel silencer with a dedicated stainless steel link pipe delivers the throttle response and power delivery that circuit riding demands — in a package that sounds every bit as aggressive as it looks.

Key Features

• Race-engineered carbon fibre and stainless steel GP-Classic silencer (part no. BW27094SO05) sheds meaningful unsprung weight for improved handling dynamics on track.
• Stainless steel link pipe (part no. BW2709430I) optimises exhaust flow and ensures a precise, durable fit specific to the K67 chassis.
• Improved throttle response and enhanced power delivery throughout the rev range — exactly what a circuit session requires.
• Included DB-killer insert allows noise-level adjustment to meet different track day regulations without additional purchases.
• Aggressive GP-Classic aesthetic that complements the S1000RR's race-bred lines on the grid or in the paddock.
• Race use only — developed exclusively for closed-circuit competition, not road-legal.

Design and Build Quality

Termignoni's GP-Classic silencer pairs a carbon fibre outer canister with an internal stainless steel construction, a combination that keeps mass low without sacrificing the structural rigidity required under sustained race conditions. The carbon fibre finish is unmistakably Italian in its execution — purposeful and refined at the same time. The link pipe is manufactured entirely in stainless steel, chosen for its resistance to the thermal cycling and corrosion that track environments inevitably produce. Every joint and weld is held to the tolerances Termignoni's Italian manufacturing is known for.

Track Performance

On the BMW S1000RR K67, even marginal gains in throttle response make a measurable difference at corner exit. The GP-Classic kit reduces exhaust back-pressure compared to the stock system, freeing the inline-four to breathe more efficiently and delivering a more immediate, progressive power curve. The characteristic Termignoni exhaust note — sharp on overrun, full-throated at high revs — also serves as an audible tuning tool, helping a rider read engine behaviour through sound. The DB-killer gives circuit regulators what they need and can be removed when the regulations allow it.

Important Installation Note

The slip-on silencer (BW27094SO05) can be ordered separately, but it is only compatible when fitted together with link pipe BW2709430I. Both parts are required for correct installation on the K67 chassis. This kit is designed exclusively for closed-circuit racing and is not approved for road use.
