Spark Exhaust Full System Stainless Steel BMW M1000RR K66 (2021-2026) GBM8824T

Engineered specifically for the BMW M1000RR K66, the Spark Exhaust GBM8824T full system is a masterclass in premium materials and precision Italian craftsmanship. Stainless steel headers paired with a titanium silencer and carbon end cap slash 4.5 kg from the factory weight — transforming how this superbike handles and sounds on track.

Key Features

• Substantial weight saving of 4.5 kg over the OEM system: Spark system weighs just 5.9 kg against the stock 10.4 kg, sharpening steering response and reducing unsprung mass.
• Stainless steel headers offer exceptional durability, corrosion resistance and optimised exhaust gas flow for every rev of the S1000RR-derived inline-four.
• Titanium silencer body with carbon end cap combines the lowest possible weight with a race-bred aesthetic built to withstand sustained high-temperature use.
• Force silencer design featuring the latest-generation rib profile on the titanium shell, contoured to complement the carbon end piece — a detail that sets this system apart from previous iterations.
• DB killer (part number G9999) included and removable, giving you flexibility for paddock noise limits without any additional purchase.
• Mounting kit with dedicated rear-frame bracket included; fully compatible with OEM fairings and kit radiators so fitment is straightforward with standard tools.

Build Quality and Materials

Spark constructs every component of the GBM8824T in Italy to exacting standards. The stainless steel headers are mandrel-bent for consistent internal diameter, ensuring exhaust gases flow without restriction from the cylinder head all the way to the collector. The titanium silencer is shaped using the brand's evolved Force geometry — a refined rib detail along the body that follows the taper of the carbon fibre end cap, resulting in a cohesive, purposeful appearance that reflects the quality of construction underneath. Carbon end caps are not merely decorative here; they form a structural element of the silencer closure and are finished to a standard you would expect from a factory race programme.

Performance and Track Use

The optimised exhaust routing improves throttle response and supports increased engine output across the rev range. At approximately 104 dB measured at 5,500 rpm, the system produces a genuine race note that communicates engine load and rpm clearly — an advantage on circuit. Because this system is designed exclusively for closed-course competition, Spark recommends an ECU remap or dyno tune after installation to extract the full performance benefit and ensure correct fuelling throughout the powerband.

Important Notice

This exhaust system is intended for race track use only and is not homologated or approved for use on public roads. It is not compatible with passenger footpegs. An ECU remap or rolling-road calibration is strongly recommended following installation.
