On the right motorcycle it is the most elegant shape Spark makes.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eUniversal Trumpet silencer, AISI 304 stainless, scotch-brite finish.\u003c\/li\u003e\n\u003cli\u003e1.5 kg.\u003c\/li\u003e\n\u003cli\u003eRemovable db killer included.\u003c\/li\u003e\n\u003cli\u003eLogo lasered both sides; single or paired installation, either flank.\u003c\/li\u003e\n\u003cli\u003eBlack ceramic treatment available as an option.\u003c\/li\u003e\n\u003cli\u003eCustom marking on request.\u003c\/li\u003e\n\u003cli\u003eNot approved. Custom Works component.\u003c\/li\u003e\n\u003cli\u003eSpark part number G00SI12I, made in Mantova, Italy.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eThe Flare\u003c\/h2\u003e\u003cp\u003eMost silencers end where the case ends. The Trumpet does not: the last section opens outward into a bell, which is a period detail borrowed from megaphone exhausts of the fifties and sixties and one that almost nobody still builds.\u003c\/p\u003e\u003cp\u003eIt is harder to make than a straight cut. The bell has to be formed rather than rolled and the wall thins as it opens, which is why the shape mostly disappeared when exhaust production got cheaper.\u003c\/p\u003e\u003ch2\u003eWhich Bikes It Suits\u003c\/h2\u003e\u003cp\u003eAnything with visible frame tubes and a horizontal line: a Bonneville, a Guzzi, a big single, a cafe racer built on almost any donor. The Trumpet reads as a continuation of the frame rail, so it works where the exhaust is meant to be part of the drawing rather than tucked out of sight.\u003c\/p\u003e\u003cp\u003eOn a modern faired sports bike it does not. That is what the Konix Evo and the Grid-O are for.\u003c\/p\u003e\u003ch2\u003eSound\u003c\/h2\u003e\u003cp\u003eAn opening outlet changes the way the exhaust note leaves the case — less directional, fuller in the mid range. Spark supplies the insert in the box, so the same silencer can be run closed for the road and open for a paddock.\u003c\/p\u003e\u003ch2\u003eA Kilo and a Half\u003c\/h2\u003e\u003cp\u003eFifteen hundred grams of AISI 304, which is what a formed bell costs in weight against a plain cut. It is the price of the shape, and on the kind of motorcycle this silencer belongs to it is not a figure anybody is optimising.\u003c\/p\u003e\u003ch2\u003eCeramic if You Want It Dark\u003c\/h2\u003e\u003cp\u003eThe black ceramic treatment is offered as an option on this case, applied to order. Spark also builds a factory Black Series version under article G00SI12B if you would rather have the finish done at the works than added afterwards.\u003c\/p\u003e","brand":"Spark Exhaust","offers":[{"title":"Default Title","offer_id":53617722196234,"sku":"G00SI12I","price":67049.0,"currency_code":"ETB","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/698b427d2b361_15d14f3f-b6bc-445c-aa51-5ef7ce630395.png?v=1788342143","url":"https:\/\/inter-pace.com\/en-et\/products\/spark-exhaust-trumpet-universal-silencer-scotch-brite","provider":"Inter-Pace","version":"1.0","type":"link"}
