The Trumpet is long and even and opens at the mouth. The Sinfonia is fatter through the middle and tapers to a smaller outlet — the shape people call a cigar or a torpedo, and the one that turns up on sixties race replicas.\u003c\/p\u003e\u003cp\u003eOn a T100 the practical effect is proportion. A shorter can makes the tail of the motorcycle look shorter too, which suits a bike ridden solo with the pillion pegs off.\u003c\/p\u003e\u003ch2\u003eWhere It Ends\u003c\/h2\u003e\u003cp\u003eForward of the rear axle rather than level with it. That is worth knowing if the bike carries panniers, a rack or a top box: a shorter silencer leaves room where a long one interferes, and it also keeps the outlet away from a passenger's boot.\u003c\/p\u003e\u003ch2\u003eBrushed Stainless\u003c\/h2\u003e\u003cp\u003eAISI 304 with a brushed surface rather than polish. On a machine that already carries chrome mudguards and a chrome headlight shell, brushed stainless sits a half-step down in brightness, which stops the exhaust competing with the parts that are supposed to shine.\u003c\/p\u003e\u003cp\u003eThe black ceramic version of the same pair, if you want the opposite effect, is GTR0206B.\u003c\/p\u003e\u003ch2\u003eThe Sound of a Shorter Can\u003c\/h2\u003e\u003cp\u003eLength and packing volume are what a silencer works with, and the Sinfonia has less of both than the Trumpet. As a rule that gives a harder, more immediate note rather than a deeper one — the difference between a bark and a rumble.\u003c\/p\u003e\u003cp\u003eNeither is quieter in any meaningful sense; both are racing silencers on a bike that left the factory heavily muffled. If sound is the reason you are here, the shape decides the character rather than the volume.\u003c\/p\u003e\u003ch2\u003eSold as a Pair\u003c\/h2\u003e\u003cp\u003eA Bonneville has two silencers and Spark sells them as a pair. Replacing one and leaving the other standard would work mechanically and would look and sound wrong from the first metre, so the article covers both sides.\u003c\/p\u003e\u003ch2\u003eInstallation\u003c\/h2\u003e\u003cp\u003eSlip-on level: the standard silencers come off and Spark's go on in their place, with the header pipes untouched. On a T100 that is a bolt-on afternoon rather than a workshop job.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eTriumph Bonneville T100, 2005 to 2015. The Black Series version of this pair is GTR0206B. The longer Trumpet shape is GTR0205I and GTR0205B, and the Megaphone is GTR0207I and GTR0207D.\u003c\/p\u003e\u003ch2\u003eRoad Approval\u003c\/h2\u003e\u003cp\u003eNone. Spark lists this article as not approved, and a Bonneville is a road bike far more often than a track one.
