The headers sit high and protected behind the frame; the silencer hangs low, wide and behind the rear wheel, and in a low-side it is what meets the tarmac first.\u003c\/p\u003e\u003cp\u003eSpark selling this group separately is what keeps a twenty-six-hundred-euro system from being written off by one fall. The titanium headers stay on the motorcycle, and one part number puts the exhaust back together.\u003c\/p\u003e\u003ch2\u003eDesigned to Pass a Sound Check\u003c\/h2\u003e\u003cp\u003eSpark states that the internal volume of this silencer ensures effective noise reduction, complying with the sound regulations of major European circuits. That is a design intention, not an approval — the system it belongs to carries no EC certificate.\u003c\/p\u003e\u003cp\u003eThe distinction matters at a circuit gate. What Spark is saying is that the silencer measures inside typical limits as supplied, rather than needing a plug to get there. The G9999 dB killer is offered for riders who want finer control still.\u003c\/p\u003e\u003ch2\u003eNot a Slip-On\u003c\/h2\u003e\u003cp\u003eThis is the silencer group from a full titanium system, and it is dimensioned for that system's link pipe. It is not a slip-on for the standard Triumph exhaust and will not mount to one.\u003c\/p\u003e\u003cp\u003eIf your Trident still has its original headers, the part you want is one of the homologated full systems — GTR8830IOM or GTR8831TOM for the 2025 machines — rather than this group on its own.\u003c\/p\u003e\u003ch2\u003eWhat a Force Evo Is\u003c\/h2\u003e\u003cp\u003eThe Force Evo is the evolution of Spark's long-serving Force silencer: a titanium case with a rib running the length of the sleeve and converging into the lines of the carbon fibre end cap.\u003c\/p\u003e\u003cp\u003eWithin Spark's range it is the case chosen when a sound limit is part of the brief — the same silencer the company fits to its Endurance World Championship system. On a WSPB kit built to a class rulebook, that is the logical choice rather than the compromise one.\u003c\/p\u003e\u003ch2\u003eBuying a Second Silencer\u003c\/h2\u003e\u003cp\u003eDamage is not the only reason to order this number. Because the group mounts to the same link pipe as the one supplied with the complete system, owning two is a practical way to run one exhaust at two sound levels.\u003c\/p\u003e\u003cp\u003eFor a rider who books circuits with different published limits, that is cheaper and quicker than any alternative — and it leaves the expensive titanium headers untouched on the motorcycle.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eTriumph Trident 660 and Tiger Sport 660, 2025 through 2026, on Spark's WSPB full titanium system.
