Spark Exhaust Moto GP Homologated Full System Ceramic Box Dark Silencer Triumph Trident 660 / Tiger Sport 660 / Daytona 660 (2021-2026) GTR8819DOM

Two dark finishes, applied where each one belongs. Spark treats the pre-silencer box with black ceramic and fits a dark-style Moto GP silencer behind it — the middle rung between the plain stainless system and the full Black Series.

Key Features

• Homologated full system for the Triumph Trident 660, Tiger Sport 660 and Daytona 660.
• Black ceramic treatment on the pre-silencer box.
• Moto GP silencer in dark style.
• Racing catalytic converter with high noble-metal loading.
• Certificate from the Italian Ministry of Transport.
• Between the stainless and Black Series versions in price.

Two Kinds of Dark, and Why

Spark uses different treatments on different components because the components are different metals doing different jobs. The box is stainless steel, sits low and takes the worst of what the road throws up; ceramic bonds well to it and survives being blasted with grit and salt.

The silencer is a separate assembly with its own surface, and Spark's dark style is how it finishes that. Reading the price list, the material column for this article says dark style and the description mentions the ceramic box — both are true, and they refer to different parts of the same exhaust.

Where Each Finish Earns Its Money

The box is the component that discolours first. It runs hot, it is the largest visible surface in the system, and on a Trident it hangs in plain view under the engine. Bare stainless there goes blue-brown within a season.

The silencer sits higher and further back, and it is what people look at. A dark case there is a styling decision rather than a protective one. Between them the system stays uniform without paying for the full Black Series treatment.

What It Does Not Change

The mechanical specification is the standard homologated system: an AISI 304 collector and box, a racing catalytic converter heavily impregnated with noble metals, and the same certificate from the Italian Ministry of Transport.

Spark publishes the homologation numbers the certificate covers. Check them against your vehicle documents before ordering — the approval is tied to those numbers, not to the finish.

Three Motorcycles Share It

Spark lists this system for the Trident 660, the Tiger Sport 660 and the Daytona 660 of the same generation. All three use the same three-cylinder and the same exhaust interface.

The finish reads differently on each. On a Tiger Sport, where panniers and bodywork already fill the rear view, the dark system disappears entirely. On a Trident it keeps the bike's clean line intact. On a Daytona in a bright colour it becomes a deliberate contrast under the tail.

Fitment & Compatibility

Triumph Trident 660, Tiger Sport 660 and Daytona 660, 2021 through 2026. The plain stainless Moto GP system is GTR8818TOM; the full Black Series is GTR8818BOM. With the 60's silencer and a ceramic box the system is GTR8819BOM.
