DescriptionThe whole story▼
The silencer from Spark's WSPB titanium system, sold on its own. A fraction of the price of the complete part — the one to order when a case has been damaged and the headers came through it.
Key Features
- Force Evo silencer group for the Triumph Trident 660 and Tiger Sport 660, 2025 to 2026.
- Titanium with a carbon fibre end cap.
- From Spark's WSPB full titanium system.
- Internal volume designed to meet the sound regulations of major European circuits.
- Takes the optional G9999 dB killer.
- Around a quarter of the price of the complete system.
The Part That Gets Damaged
An exhaust does not wear evenly. 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.
Spark selling this group separately is what keeps an expensive system from being written off by one fall. The titanium headers stay on the motorcycle, and one part number puts the exhaust back together.
Designed to Pass a Sound Check
Spark 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.
The 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.
Not a Slip-On
This 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.
If 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.
What a Force Evo Is
The 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.
Within 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.
Buying a Second Silencer
Damage 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.
For 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.
