Every component — from the header to the silencer sleeve — reflects Austin Racing's obsession with material quality, longevity under extreme heat, and unrestricted exhaust flow. This is a system designed and constructed to perform at the limit, session after session.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFull titanium construction throughout — exceptional heat resistance, dramatically reduced weight and a finish that ages gracefully under track conditions\u003c\/li\u003e\n\u003cli\u003eDe-cat replacement pipe removes the catalytic converter to deliver unrestricted exhaust flow and unlock the engine's full potential\u003c\/li\u003e\n\u003cli\u003eChoice of GP1R (60 mm outlet) or V3 (150 mm or 200 mm can) silencer bodies to suit your sound and power preferences\u003c\/li\u003e\n\u003cli\u003eInternal baffling technology allows volume adjustment — genuinely configurable track noise levels\u003c\/li\u003e\n\u003cli\u003eCompatible with pillion footpegs, so your machine remains versatile between track days and road use\u003c\/li\u003e\n\u003cli\u003eThree logo finish options — standard sticker, laser engraved, or colour laser engraved — for a personalised, race-quality appearance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eConstruction and Materials\u003c\/h2\u003e\u003cp\u003eAustin Racing builds this system to a standard that justifies its provenance. The header is a full titanium fabrication — not a titanium-coated steel item — which keeps mass at the front of the exhaust to a minimum while handling the intense thermal cycling of repeated track use without warping or discolouration beyond the characteristic titanium patina. The GP1R silencer pairs a titanium body with a carbon sleeve, while the V3 is available in either titanium or black ceramic finish, both chosen for their resistance to the sustained heat generated at race RPM.\u003c\/p\u003e\u003cp\u003eThe de-cat replacement pipe is a direct substitute for the original catalytic converter section, maintaining the correct fitment geometry while opening up flow that the standard unit restricts. Unlike universal de-cat solutions, this is an Austin Racing-specified piece engineered to integrate with the GP3 header and silencer without compromise.\u003c\/p\u003e\u003ch2\u003eSilencer Options in Detail\u003c\/h2\u003e\u003ch3\u003eGP1R Silencer\u003c\/h3\u003e\u003cp\u003eThe GP1R uses a 60 mm end outlet and is available in black or titanium finish. The carbon sleeve adds a further weight saving over a metal-bodied unit and provides the visual identity most closely associated with Austin Racing's competition-derived catalogue.\u003c\/p\u003e\u003ch3\u003eV3 Silencer\u003c\/h3\u003e\u003cp\u003eThe V3 offers a choice of 150 mm or 200 mm canister sizes in black ceramic or titanium. The larger format gives a deeper, more authoritative exhaust note while the black ceramic finish provides a durable, heat-stable surface that stands up to repeated track days without fading.\u003c\/p\u003e\u003ch2\u003eSound Performance\u003c\/h2\u003e\u003cp\u003eBoth silencer options use Austin Racing's internal baffling technology, which allows the rider to adjust the output volume to suit circuit noise regulations or personal preference. Measured dB values at 5,500 RPM for both the GP1R and V3 are to be confirmed — contact Inter-Pace for the latest figures before purchase if noise compliance is a factor for your circuit.\u003c\/p\u003e\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\u003cp\u003eFitting the GP3 system to the S1000RR K67 requires cutting the original exhaust system to accommodate the new header section. This is a permanent modification and should be carried out by a competent mechanic familiar with the BMW exhaust architecture. A servo eliminator (SERVO-PLUG) is required to prevent electronic fault codes from appearing on the dashboard once the de-cat pipe is installed — this item is not included and must be sourced separately. To realise the full performance gain from this system, an ECU race map or Power Commander (PCV) fuel map is strongly recommended; the de-cat and improved flow characteristics demand a corresponding fuelling correction for optimal torque delivery and throttle response.\u003c\/p\u003e\u003cp\u003eThis exhaust system is intended exclusively for closed-circuit, track use and is not road-legal.
