Austin Racing GP3 Full Titanium Exhaust System – BMW S1000RR K67 (2019-2026)

Constructed entirely from aerospace-grade titanium and carbon, the Austin Racing GP3 full exhaust system for the BMW S1000RR K67 (2019–2026) represents the pinnacle of track-day engineering. Every component — from the headers to the silencer sleeve — is chosen for its exceptional strength-to-weight ratio, delivering a dramatic mass reduction over the stock system and a raw, unmistakable racing note that signals serious intent.

Key Features

• Full titanium and carbon construction throughout, offering extreme heat resistance and outstanding durability under sustained race conditions
• De-cat design removes all catalytic components for unrestricted exhaust flow and maximum power delivery across the rev range
• Significant weight saving over the OEM system, improving front-to-rear balance and overall handling response
• Fully configurable build: choose your header material, silencer model, end-cap finish, and logo engraving to create a bespoke setup
• Compatible with passenger footpeg hangers, retaining full flexibility for road-to-track conversion bikes
• Servo eliminator (sold separately) required to prevent ECU fault codes — plug-and-play installation once fitted

Materials and Build Quality

Austin Racing has built its global reputation on uncompromising material selection, and the GP3 system is no exception. Headers are available in grade titanium or AR22 Inconel — the latter a nickel-chromium superalloy used in extreme heat and high-stress race environments where standard titanium would be pushed to its limits. The silencer body is available in titanium or black-anodised titanium, paired with a carbon sleeve on GP1R configurations that adds rigidity while shaving additional grams. Every weld, every joint, every fitment point reflects the exacting standards expected of a system manufactured in England and developed on circuit.

Configuration Options

Header Material

Titanium: ultralight, proven in racing and resistant to the sustained high temperatures of a performance four-cylinder. AR22 (Inconel): the choice for endurance or extreme-performance applications demanding the ultimate in thermal and mechanical resilience.

Silencer Models

GP1R: 60 mm outlet, available in black or titanium finish, with a carbon sleeve body for maximum durability and a purposeful, premium aesthetic. V3: available in 150 mm or 200 mm configurations in black or titanium, offering a deeper, more forceful exhaust note suited to high-output track use.

End-Cap Colours

• GP1R: black or titanium
• V3: black only

Logo Options

• GP1R: standard sticker, laser engraving, or colour laser engraving
• V3: laser engraving or colour laser engraving

Sound and Performance

The GP3 system has been developed and validated on circuit with tested decibel figures. The GP1R without db-killer produces an aggressive, high-volume race tone with no mechanical restriction. The V3 in either 150 mm or 200 mm specification delivers a powerful, full-pressure sound character suited to uncompromising track performance. Both configurations benefit from the de-cat header design, ensuring exhaust gases exit as freely as the engine can produce them.

ECU Tuning Recommendation

To unlock the full performance potential of your BMW S1000RR K67 (2019–2026) with this system fitted, an ECU remap or Power Commander V (PCV) fuelling calibration is strongly recommended. Proper fuelling calibration ensures clean throttle response, optimal power delivery at every point in the rev range, and protection of engine internals under race conditions. A servo eliminator plug is required to prevent electronic fault messages related to the exhaust valve servo — this is a mandatory step for correct system operation.

Fitment and Compatibility

This exhaust system is designed and manufactured specifically for the BMW S1000RR K67, covering the 2019, 2020, 2021, 2022, 2023, 2024, 2025, and 2026 model years. It is not compatible with earlier S1000RR generations. This system is intended exclusively for closed-circuit racing use and is not road-legal or type-approved for public roads.
