Spark Exhaust Grid-O Titanium Full Exhaust System BMW S1000RR K67 (2019-2026) GBM8823

Every gram matters on track, and the Spark Exhaust Grid-O Titanium full exhaust system for the BMW S1000RR K67 (2019-2026) strips 6.8 kg from the stock system — dropping from 10.5 kg to just 3.7 kg — through an all-titanium construction that is as durable as it is featherlight. Header, silencer body and end cap are each machined and welded from titanium, the material of choice for factory race programmes, delivering thermal resistance and structural integrity that aluminium or stainless alternatives simply cannot match at this weight.

Key Features

• Massive 6.8 kg weight saving over the OEM system (10.5 kg down to 3.7 kg), sharpening chassis dynamics and improving acceleration response throughout the rev range.
• Full titanium construction throughout — header, silencer body and end cap — for exceptional strength-to-weight ratio and long-term resistance to heat and corrosion.
• Race-spec 114 dB output at 5,500 rpm (without db-killer) engineered for championships and track days with no noise restrictions.
• Removable db-killer (G9980, included) lets you dial back the volume for road use or compliant track days without removing any other components.
• Fully compatible with standard fairings and both OEM and aftermarket radiators — no bodywork modifications required.
• Supplied with a bracket for the original pillion footpeg, making the system equally viable on road-registered machines.
• Handcrafted in Italy, complete with all exhaust springs and the full installation hardware kit.

Build Quality & Materials

Spark Exhaust has built its reputation on precision Italian craftsmanship, and the Grid-O exemplifies that philosophy. The header pipes are formed from lightweight titanium tube, hand-TIG-welded to a fitment standard that ensures zero leaks and consistent gas flow. The silencer canister continues the theme: a pure titanium shell that resists discolouration under sustained hard use far better than steel, while the titanium end cap completes a cohesive, aesthetically purposeful package. The result is a system that looks as purposeful as it performs.

Performance & Sound

Designed explicitly for racing series operating without decibel restrictions, the Grid-O delivers an aggressive, free-revving exhaust note that reflects the reduced back-pressure and improved scavenging the titanium pipework provides. Without the db-killer the system measures 114 dB at 5,500 rpm. Reinsert the included G9980 db-killer and the note is tamed sufficiently for controlled-noise environments. To extract the full performance potential, Spark and Inter-Pace strongly recommend a dedicated race map or dyno session calibrated to the open exhaust.

Fitment & Compatibility

This full exhaust system is a direct fitment for the BMW S1000RR K67 covering model years 2019 through 2026. It is compatible with standard OEM fairings and both factory and aftermarket radiators. An optional chassis bracket is available for further customisation. The included pillion footpeg bracket retains OEM-style functionality, making installation straightforward on both track-only and road-registered bikes.
