Spark Exhaust Force Racing Full System 350 mm Titanium Honda CBR 1000 RR (2008-2019) GHO8822T

102 decibels. That is the number this system was built around, because the teams who asked Spark for it race in the World Endurance Championship, where a circuit noise limit ends your weekend just as surely as a broken engine does.

Key Features

• Racing full system for the Honda CBR 1000 RR, 2008 to 2019.
• AISI 304 stainless steel collector, designed to optimise gas delivery.
• Force silencer in titanium, 350 mm case.
• 102 dB measured — the quietest of the four silencer options for this collector.
• 4,7 kg against 7,2 kg standard: 2,5 kg saved.
• 2008 to 2016 machines need the SGATT837 hanger, sold separately.

Developed for Endurance Racing

Spark states where this system came from: teams competing in the World Endurance Championship asked for a product that would deliver top performance and survive a 24-hour race, while staying inside the decibel limits. Those are three requirements that pull against each other, and the collector is where Spark resolved them.

Endurance is also the reason the construction is stainless rather than titanium at the front. A collector that has to survive a full season of racing and several rebuilds is not the place to save the last few hundred grams.

Four Silencers, Four Decibel Figures

Spark publishes a measured figure for every silencer that fits this collector, which is more than most manufacturers do: Force 300 mm at 103,2 dB, Force 350 mm at 102 dB, MotoGP at 113 dB and Konix at 106 dB.

This article is the 350 mm Force, the quietest of the four. A longer case is a quieter case, and if the tracks you ride enforce a strict phonometric limit, that is the entire argument. Spark adds that a dB killer can be fitted to any of the silencers for a further reduction.

Two things change on a 2008 to 2016 machine. First, the system needs the SGATT837 hanger to mount — a stainless bracket Spark sells separately at 46 euro. Second, Spark warns that on those model years the collector runs close to the oil filter, and the exhaust has to come off to change it.

That is not a fault, it is a consequence of where Honda put the filter on the earlier engine. But it is worth knowing before the first service rather than after.

Two and a Half Kilos

7,2 kg standard against 4,7 fitted. On a litre superbike that is a meaningful fraction of the unsprung and high-mounted mass, and it comes almost entirely from replacing the standard silencer and its heavy catalytic section with a titanium case.

Track Use Only

Spark lists this system as not approved. It carries no homologation certificate and no catalytic converter, and it must not be fitted to a motorcycle ridden on public roads. The 102 dB figure is about circuit regulations, not road law.

Fitment & Compatibility

Honda CBR 1000 RR, 2008 to 2019. Machines from 2008 to 2016 additionally need hanger SGATT837. The same collector with the Konix silencer is GHO8824T at 1.844 euro and measures 106 dB.

Road Approval

None. Spark lists this system as not approved; it is built for closed-circuit use and must not be fitted to a motorcycle ridden on public roads.
