Built entirely in Italy with titanium headers and a Konix Evo slip-on silencer capped in carbon, part number GBM8821 is engineered without compromise for track-day and race use.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDramatic 6 kg weight reduction — from 10.4 kg to just 4.4 kg — improving chassis dynamics, turn-in response and acceleration out of slow corners.\u003c\/li\u003e\n\u003cli\u003eFull titanium header and silencer construction delivers outstanding heat resistance alongside exceptional strength-to-weight ratio.\u003c\/li\u003e\n\u003cli\u003eCarbon silencer end cap adds rigidity and a purposeful race aesthetic.\u003c\/li\u003e\n\u003cli\u003eRemovable DB-killer lets you dial the sound level to suit circuit regulations; sound level is approximately 107 dB at 5,500 rpm with the DB-killer removed.\u003c\/li\u003e\n\u003cli\u003eRetains compatibility with original fairings and both standard and kit-specification radiators for a straightforward installation.\u003c\/li\u003e\n\u003cli\u003eMade in Italy — hand-finished to the exacting standards Spark Exhaust is known for in professional motorsport.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003ePerformance \u0026amp; Build Quality\u003c\/h2\u003e\u003cp\u003eThe titanium headers are mandrel-bent for optimal gas flow, feeding directly into the Spark Konix Evo silencer — a canister proven on European Superbike circuits. Titanium's natural resistance to the extreme temperatures generated by the M1000RR's four-cylinder engine means the system stays dimensionally stable lap after lap. The carbon end cap keeps radiated heat away from surrounding bodywork while trimming every last gram possible.\u003c\/p\u003e\u003cp\u003eThe 6 kg mass reduction is not just a headline figure. Removing unsprung and low-slung weight from the tail section noticeably sharpens the bike's willingness to change direction and allows the suspension to track the tarmac more accurately. Combined with the improved throttle response that a free-flowing full system provides, the GBM8821 makes the M1000RR feel genuinely quicker everywhere on the circuit, not only at peak revs.\u003c\/p\u003e\u003ch2\u003eInstallation \u0026amp; Compatibility Notes\u003c\/h2\u003e\u003cp\u003eThe system is supplied with a complete mounting kit including the bracket needed to secure the silencer to the original sub-frame — no fabrication required. It is compatible with standard fairings and with both OEM and aftermarket kit radiators. Note that this system is not compatible with the passenger footpegs; it is intended exclusively for single-seat track configuration. For maximum power gains, a dedicated race ECU map or a custom dyno tune is strongly recommended to take full advantage of the unrestricted exhaust flow.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eThis full exhaust system fits the following model:\u003c\/p\u003e\u003cul\u003e\u003cli\u003eBMW M1000RR K66 (2021, 2022, 2023, 2024, 2025, 2026)\u003c\/li\u003e\u003c\/ul\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003ePart Number\u003c\/th\u003e\n\u003ctd\u003eGBM8821\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eSpark Exhaust\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eType\u003c\/th\u003e\n\u003ctd\u003eFull system (header + silencer)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSilencer Model\u003c\/th\u003e\n\u003ctd\u003eKonix Evo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHeader Material\u003c\/th\u003e\n\u003ctd\u003eTitanium\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSilencer Material\u003c\/th\u003e\n\u003ctd\u003eTitanium\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eEnd Cap Material\u003c\/th\u003e\n\u003ctd\u003eCarbon\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWeight Saving\u003c\/th\u003e\n\u003ctd\u003e-6 kg (10.4 kg stock → 4.4 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSound Level\u003c\/th\u003e\n\u003ctd\u003eapprox. 107 dB at 5,500 rpm (DB-killer removed)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDB-Killer\u003c\/th\u003e\n\u003ctd\u003eRemovable, included\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eOrigin\u003c\/th\u003e\n\u003ctd\u003eMade in Italy\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFitment\u003c\/th\u003e\n\u003ctd\u003eBMW M1000RR K66 (2021–2026)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Spark Exhaust","offers":[{"title":"Default Title","offer_id":53168854860042,"sku":"GBM8821","price":2357.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/GBM8821_71ea2f4e-f379-4710-837b-5899ce3498c2.png?v=1780817782","url":"https:\/\/inter-pace.com\/products\/spark-exhaust-titanium-full-system-bmw-m1000rr-k66-gbm8821","provider":"Inter-Pace","version":"1.0","type":"link"}
