Built in Italy and engineered specifically for the K66 M1000RR, this complete header-to-silencer solution offers track-focused performance with enough everyday versatility to make it a sensible choice for road riders who want more from their machine without sacrificing daily usability.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e6 kg weight reduction over the stock exhaust — chassis balance and acceleration both benefit immediately\u003c\/li\u003e\n\u003cli\u003eSpark Force Evo slip-on silencer in titanium, updated with a new rib on the titanium shell that follows the line of the carbon end cap for a cohesive, purposeful look\u003c\/li\u003e\n\u003cli\u003eFull titanium headers — high strength, low mass, and excellent thermal resistance for sustained hard riding\u003c\/li\u003e\n\u003cli\u003eCarbon end cap adds rigidity to the system while keeping the overall weight in check\u003c\/li\u003e\n\u003cli\u003eRemovable DB Killer (G9999) included — run it for road use, pull it for the track; measured at 104 dB at 5,500 rpm without the insert\u003c\/li\u003e\n\u003cli\u003eMade in Italy — hand-finished craftsmanship underpins every weld and joint\u003c\/li\u003e\n\u003cli\u003eComplete mounting kit included with bracket for fitting the silencer to the original rear subframe\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eBuild Quality and Design\u003c\/h2\u003e\u003cp\u003eThe Force Evo silencer represents the latest evolution of Spark's flagship can. A redesigned rib running along the titanium body mirrors the contour of the carbon end cap, creating a visual continuity between the two materials that looks intentional rather than assembled. The carbon cover is not purely cosmetic — it contributes structural stiffness to the outlet end of the system, resisting the vibration and thermal cycling that punish lesser components over time.\u003c\/p\u003e\u003cp\u003eAll exhaust springs and the full installation hardware are included in the box. The system is compatible with the original fairings and with both the stock radiator and aftermarket radiator kits. Note that this system is not compatible with the pillion footrest — riders who regularly carry a passenger should factor this into their decision.\u003c\/p\u003e\u003ch2\u003ePerformance and Sound\u003c\/h2\u003e\u003cp\u003eThe weight saving alone justifies the investment for many riders: 6 kg removed from a high-mounted position improves the centre of gravity, reduces unsprung and reciprocating mass effects, and sharpens throttle response. Spark recommends pairing the system with a dedicated race ECU map or a dyno session to unlock the full potential of the freer-flowing exhaust. Without a remap the gains are real; with one, they are substantially greater.\u003c\/p\u003e\u003cp\u003eSound level is 104 dB at 5,500 rpm with the DB Killer removed. With the DB Killer fitted the system remains road-usable for most jurisdictions, making this one of the more practical titanium full systems available for the M1000RR.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThis full exhaust system is designed exclusively for the BMW M1000RR K66 covering model years 2021 to 2026. It fits with the original BMW fairings and with both OEM and aftermarket radiator kits. It is not compatible with the pillion\/passenger footrest. A race map or dyno tune is strongly recommended to maximise performance after installation.\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePart numbers: GBM8821 (headers) + GBM8824ST (silencer)\u003c\/li\u003e\n\u003cli\u003eSystem type: Full system (complete exhaust)\u003c\/li\u003e\n\u003cli\u003eFitment: BMW M1000RR K66 (2021-2026)\u003c\/li\u003e\n\u003cli\u003eHeader material: Titanium\u003c\/li\u003e\n\u003cli\u003eSilencer material: Titanium\u003c\/li\u003e\n\u003cli\u003eEnd cap material: Carbon\u003c\/li\u003e\n\u003cli\u003eWeight of system: 4.4 kg (saving of 6 kg vs. stock 10.4 kg)\u003c\/li\u003e\n\u003cli\u003eSound level: 104 dB at 5,500 rpm (DB Killer removed)\u003c\/li\u003e\n\u003cli\u003eDB Killer: Removable (part number G9999), included\u003c\/li\u003e\n\u003cli\u003eCountry of manufacture: Italy\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Spark Exhaust","offers":[{"title":"Default Title","offer_id":53168854663434,"sku":"GBM8821+GBM8824ST","price":2440.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/GBM8821_61394f04-e3c5-42b3-8744-471a4e2ba48b.png?v=1780817770","url":"https:\/\/inter-pace.com\/products\/spark-exhaust-titanium-full-system-bmw-m1000rr-k66-gbm8821-gbm8824st","provider":"Inter-Pace","version":"1.0","type":"link"}
