When it does come up it is a chamber or a box that has to change direction around a structural member, and there is no smaller way of doing it.\u003c\/p\u003e\u003cp\u003eThat rarity is why it is worth knowing the article exists. A project that needs it needs it absolutely.\u003c\/p\u003e\u003ch2\u003eThe Segmented Alternative\u003c\/h2\u003e\u003cp\u003eA pie-cut bend — wedges cut from a straight tube and welded back together — produces any angle at any diameter. It also produces a faceted bore, six times the weld length, more weight and less consistency than a formed part.\u003c\/p\u003e\u003cp\u003eOn a visible section of a custom exhaust the mandrel bend wins on every count except availability, which is precisely what stocking one solves.\u003c\/p\u003e\u003ch2\u003eSweep, Not Angle\u003c\/h2\u003e\u003cp\u003eAt this diameter the arc matters more than the number. A forty-five degree bend in seventy-six millimetre tube occupies a great deal more room than the figure suggests, and on a motorcycle that room is generally shared with the rear wheel. Draw it before ordering.\u003c\/p\u003e\u003ch2\u003eBore Consistency\u003c\/h2\u003e\u003cp\u003eThe point of a mandrel at this size is that the bore stays the same all the way round. In a chamber or a box that consistency is not about flow — it is about the inner components fitting: a perforated core pushed through a formed bend goes; through a segmented one it does not.\u003c\/p\u003e\u003ch2\u003eTwo Hands\u003c\/h2\u003e\u003cp\u003eIt is large, thin relative to its diameter, and permanently marked by a dropped spanner. Clear the bench first, and put nothing else on it while the part is there.\u003c\/p\u003e\u003ch2\u003eCutting It Square\u003c\/h2\u003e\u003cp\u003eHalf a degree of error across seventy-six millimetres is more than half a millimetre of gap at the far side of the joint. A bandsaw with a proper vee support and a paper template beat an angle grinder and a steady hand by a wide margin at this diameter.\u003c\/p\u003e\u003ch2\u003eOrdering\u003c\/h2\u003e\u003cp\u003eOne bend per article. Spark builds 30°, 45° and 90° at seventy-six millimetres.\u003c\/p\u003e","brand":"Spark Exhaust","offers":[{"title":"Default Title","offer_id":53618186944778,"sku":"G9160","price":13800.0,"currency_code":"AMD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7831\/0410\/files\/6087e73b3624a_aad95a41-c8d9-42a5-a2de-128e7744abb7.png?v=1788348022","url":"https:\/\/inter-pace.com\/en-am\/products\/spark-exhaust-bent-tube-45-degrees-76mm","provider":"Inter-Pace","version":"1.0","type":"link"}
