Spark calls the shape Trumpet, and on a Bonneville it is the silhouette that changes least about the bike while changing everything about how it sounds.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePair of Trumpet slip-on silencers for the Triumph Bonneville T100, 2005 to 2015.\u003c\/li\u003e\n\u003cli\u003eAISI 304 stainless steel with a Scotch-Brite finish.\u003c\/li\u003e\n\u003cli\u003e3.5 kg for the pair.\u003c\/li\u003e\n\u003cli\u003eHeader pipes stay standard — slip-on level.\u003c\/li\u003e\n\u003cli\u003eRacing part, not approved for road use.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eThe Trumpet Silhouette\u003c\/h2\u003e\u003cp\u003eLong body, gentle taper, and a slight flare at the outlet that gives the design its name. Next to the standard T100 silencers it sits lower and finishes further back, and the line it draws along the bike is the one classic British twins have had since before either of us was riding.\u003c\/p\u003e\u003cp\u003eIt is the most conservative of the three shapes Spark offers here. If the point is to keep the Bonneville looking like a Bonneville, this is the pair to fit.\u003c\/p\u003e\u003ch2\u003eScotch-Brite, Not Chrome\u003c\/h2\u003e\u003cp\u003eThe stainless is finished with a Scotch-Brite brush rather than polished. That is a deliberate choice on a retro bike: brushed stainless catches light in a soft, uneven way that reads as period-correct, where chrome reads as new.\u003c\/p\u003e\u003cp\u003eIt also ages better. A brushed surface takes a scratch and blends it; a polished one shows every mark for the rest of its life.\u003c\/p\u003e\u003ch2\u003eWhat a Slip-On Changes\u003c\/h2\u003e\u003cp\u003eEverything behind the header pipes. Spark quotes 3.5 kg for the pair, and the standard T100 silencers are heavier steel cans with more internal baffling.\u003c\/p\u003e\u003cp\u003eThe sound is the real reason people fit these. A 865 cc parallel twin with a 360-degree crank has a specific off-beat pulse that the standard system muffles into nothing, and a straighter silencer lets it through.\u003c\/p\u003e\u003ch2\u003eNot Approved, and What That Means Here\u003c\/h2\u003e\u003cp\u003eSpark lists this article as a racing part. There is no type approval to show at a roadside check and none for the periodic inspection, and a Bonneville is a bike people ride on the road far more than on a circuit.\u003c\/p\u003e\u003cp\u003eWorth being clear about before ordering: this is a track and show part. If you need papers for a T100, the homologated Spark range starts with the later Street Twin.\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 same Trumpet pair in Spark's black ceramic finish is GTR0205B. The other two silhouettes for this motorcycle are the Sinfonia, GTR0206I and GTR0206B, and the Megaphone, GTR0207I and GTR0207D.\u003c\/p\u003e\u003ch2\u003eRoad Approval\u003c\/h2\u003e\u003cp\u003eNone.
