Spark modified the header in both length and diameter to optimise gas flow and improve engine response, and developed a new racing catalytic converter with a heavier noble-metal impregnation to satisfy the standard. Those are new parts, not recertified ones — which is why the earlier system cannot simply be relabelled for a 2025 bike.\u003c\/p\u003e\u003ch2\u003eWhere the Ceramic Goes\u003c\/h2\u003e\u003cp\u003eSpark applies the black ceramic treatment to the pre-silencer box, and fits a dark-style silencer behind it. The two are different treatments because they are different components.\u003c\/p\u003e\u003cp\u003eThe box is the large stainless surface hanging in plain view under the engine, and it is the part that discolours first — bare stainless goes blue-brown around the hottest section within a season. Ceramic bonds to it and survives the grit and salt a low component collects. The silencer is a separate assembly, and dark style is how Spark finishes that.\u003c\/p\u003e\u003ch2\u003eSame Price, Different Motorcycle\u003c\/h2\u003e\u003cp\u003eSpark charges identically for this and the Scotch-Brite stainless GTR8831TOM. Nothing mechanical differs, so the choice is only about how the exhaust should read against the bodywork.\u003c\/p\u003e\u003cp\u003eBrushed stainless makes the collector part of the motorcycle's shape. The darkened version lets the bike carry the colour and leaves the exhaust as an outline. On a Trident in a dark colourway the second is usually the more coherent result.\u003c\/p\u003e\u003ch2\u003eReady as Supplied\u003c\/h2\u003e\u003cp\u003eSpark developed this configuration to maximise power and delivery without any modification to the mapping or the ECU. No dyno time, no flashed map, no error codes.\u003c\/p\u003e\u003cp\u003eFor a motorcycle still inside its warranty period, and serviced by a dealer, that is worth more than any figure on a chart.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eTriumph Trident 660 and Tiger Sport 660, 2025 through 2026.
