Spark Exhaust Moto GP Homologated Full System Black Series Triumph Trident 660 / Tiger Sport 660 / Daytona 660 (2021-2026) GTR8818BOM

Spark's Black Series: the whole system in one dark finish rather than a dark silencer on a bright collector. It is the most expensive of the three Moto GP versions and the only one where nothing catches light.

Key Features

• Homologated full system for the Triumph Trident 660, Tiger Sport 660 and Daytona 660.
• Black Series finish across collector, pre-silencer box and silencer.
• Moto GP silencer.
• Racing catalytic converter, heavily impregnated with noble metals.
• Certificate from the Italian Ministry of Transport.
• Around two hundred and seventy euros above the stainless version.

Three Finishes, Three Prices

Spark builds this exact system in three ways and prices them apart, which makes the ladder easy to read. The stainless version with a titanium silencer is the base. The dark-style silencer costs the same. The Black Series, this one, adds around two hundred and seventy euros.

That is not a specification difference. The collector, the box, the catalyst, the silencer and the certificate are identical across all three. What the money buys is the ceramic treatment and the darker silencer together, applied so the system reads as one object rather than as two materials bolted together.

Why Ceramic Rather Than Paint

The Black Series finish is a ceramic layer cured onto the metal. On an exhaust that matters more than it would anywhere else on a motorcycle.

Paint on a component that goes from cold to several hundred degrees and back on every ride blisters, lifts at the edges and eventually flakes off around the hottest section. A baked ceramic coating does none of that, and it does not go through the blue-brown tinting bare stainless develops. Three winters later it looks the way it did in the crate.

What Stays the Same

Underneath the finish this is the standard homologated system: an AISI 304 collector and pre-silencer box, a racing catalytic converter with heavy noble-metal loading, and a certificate issued by the Italian Ministry of Transport.

Spark publishes the homologation numbers that certificate covers so owners can match them against their vehicle documents before ordering. The approval is specific to those numbers, whatever colour the system is.

The Silencer It Ends With

The Moto GP is Spark's shortest case — round, compact, with a large outlet diameter chosen to emphasise the engine note rather than absorb it. In the Black Series finish it stops being an object and becomes an outline.

On a 660 triple that shape works particularly well. The firing order gives the engine a sound with a lot of character and little bulk, and a short case with a wide exit lets more of it through unaltered. The catalysed box ahead of it is what keeps the whole system inside the regulation.

Fitment & Compatibility

Triumph Trident 660, Tiger Sport 660 and Daytona 660, 2021 through 2026. The stainless version is GTR8818TOM and the dark-style GTR8818DOM. With the 60's silencer in Black Series the system is GTR8819BOM. For the 2025 machines the equivalent is GTR8831DOM.
