It is a different angle from every other Spark family — 18° on the old round cases, 34° on the newer round and Megaphone ones — and the angles are not close enough to force.\u003c\/p\u003e\u003cp\u003eIf the plug you have does not sit flush, you have the wrong article. That is the whole diagnosis.\u003c\/p\u003e\u003ch2\u003eAlready Included, Usually\u003c\/h2\u003e\u003cp\u003eSpark ships the GP Style universal silencer with a removable db killer in the box. This article is the replacement: for the one that was lost during a rebuild, the one that stayed in a previous owner's toolbox, or the second one needed when a build runs two cases.\u003c\/p\u003e\u003cp\u003eIt is worth knowing before ordering. If your silencer is new and still boxed, the insert is already in there.\u003c\/p\u003e\u003ch2\u003eOpen Rather Than Perforated\u003c\/h2\u003e\u003cp\u003eA straight-through restriction rather than a holed wall. The GP Style is a long, slim case with plenty of internal length to work with, so Spark took the simpler route: narrow the exit and let the case do the rest.\u003c\/p\u003e\u003cp\u003eThe result is less loss of flow than a perforated insert of the same bore, and a slightly smaller reduction in noise.\u003c\/p\u003e\u003ch2\u003eWhat It Does Not Change\u003c\/h2\u003e\u003cp\u003eThe GP Style universal silencer has no homologation and cannot acquire one. The insert is a tool for getting through a circuit's noise check and for making a loud motorcycle liveable, not a route to a certificate.\u003c\/p\u003e\u003ch2\u003eForty-Seven Millimetres of Body\u003c\/h2\u003e\u003cp\u003eThe outer figure is what decides whether the insert seats at all. Forty-seven is the common size across Spark's round and GP Style cases, which is why the angle rather than the diameter is the thing that separates the articles in this part of the range.\u003c\/p\u003e\u003ch2\u003eOne Per Case\u003c\/h2\u003e\u003cp\u003eSymmetrical, so there is no left or right. A build with two GP Style cases needs two of this article.\u003c\/p\u003e","brand":"Spark Exhaust","offers":[{"title":"Default Title","offer_id":53617778917642,"sku":"G9922","price":7700.0,"currency_code":"GYD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/5b865c34c2a07_db32c89e-0add-4389-8050-a6b53c8eb8ab.png?v=1788343204","url":"https:\/\/inter-pace.com\/en-gy\/products\/spark-exhaust-db-killer-gp-style-32mm-16-degrees","provider":"Inter-Pace","version":"1.0","type":"link"}
