Its website calls it the 40 mm open insert for Grid-O silencers. Both are true: those two Triumph exhausts carry a Grid-O case, and this is the plug that belongs in it.\u003c\/p\u003e\u003cp\u003eWhich means the article is useful beyond those two numbers. Any Spark Grid-O whose outlet takes a 40 mm insert takes this one.\u003c\/p\u003e\u003ch2\u003eFour Bores in the Grid-O Family\u003c\/h2\u003e\u003cp\u003eSpark builds the Grid-O insert at 32, 38, 40 and 45 millimetres, all in the same 51.5 mm body. This is the second widest.\u003c\/p\u003e\u003cp\u003eThe bore, not the body, is what you match. If you have a Grid-O and no insert, measure what the silencer's outlet accepts before ordering — four articles look identical from the outside.\u003c\/p\u003e\u003ch2\u003eOpen Rather Than Perforated\u003c\/h2\u003e\u003cp\u003eAll four Grid-O inserts are open. The case has a woven titanium mesh across the whole outlet and does a good deal of its own work; adding a perforated plug behind a mesh would restrict without adding much attenuation.\u003c\/p\u003e\u003ch2\u003eA Genuine Spare\u003c\/h2\u003e\u003cp\u003eOn the two Triumph exhausts Spark names, this insert is part of what the customer bought. Losing it does not mean buying a new silencer — it means fifty-two euro and a screwdriver.\u003c\/p\u003e\u003ch2\u003eFifty-Two Euro Against a Silencer\u003c\/h2\u003e\u003cp\u003eThat is the arithmetic behind every article on this page. A Grid-O case is a six-hundred-gram titanium object that costs several hundred euro; the plug that makes it usable at a noise-limited circuit costs less than a tank of fuel.\u003c\/p\u003e\u003ch2\u003eApproval\u003c\/h2\u003e\u003cp\u003eWhere the exhaust it belongs to is homologated, this insert is part of the configuration that was tested and it must be fitted. Where the exhaust is a racing article, no insert changes its status.\u003c\/p\u003e","brand":"Spark Exhaust","offers":[{"title":"Default Title","offer_id":53617782784266,"sku":"G9980","price":89600.0,"currency_code":"MWK","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/699832850cfac_76fc1e47-7add-4aa5-9afc-6562a9b2f5fb.png?v=1788354092","url":"https:\/\/inter-pace.com\/en-mw\/products\/spark-exhaust-db-killer-grid-o-40mm-triumph-spare","provider":"Inter-Pace","version":"1.0","type":"link"}
