Between this bend, the 45° and 90° versions and the straight length, an entire run from collector to case can be assembled without a bender anywhere in the workshop.\u003c\/p\u003e\u003ch2\u003eThe Last Bend Before the Silencer\u003c\/h2\u003e\u003cp\u003eThirty degrees is very often the final correction: the collector is fixed, the silencer mount is fixed, and a shallow lean is what makes the two meet. Getting that bend clocked correctly is what decides whether the case sits parallel to the swingarm or slightly nose-down.\u003c\/p\u003e\u003cp\u003eTape the assembly together, sit on the motorcycle, and look at it from three metres before any heat goes near it.\u003c\/p\u003e\u003ch2\u003eGas Speed at Sixty\u003c\/h2\u003e\u003cp\u003eSixty millimetres is generous. It suits a litre-class four, a large V-twin, or anything with a pre-silencer box ahead of it. On a middleweight it costs bottom-end response, and no choice of silencer afterwards recovers that.\u003c\/p\u003e\u003cp\u003eDiameter is the decision that cannot be undone later without rebuilding the system, so it is worth spending time on before anything is cut.\u003c\/p\u003e\u003ch2\u003eHandling a Large Thin Bend\u003c\/h2\u003e\u003cp\u003eAt sixty millimetres with a one millimetre wall the piece dents if it is dropped on a corner and goes oval if it is clamped hard. Support it along its length and clamp only on the straight tangents.\u003c\/p\u003e\u003ch2\u003eInside the Bend After Welding\u003c\/h2\u003e\u003cp\u003eHeat tint forms inside a joint as readily as outside, and inside a curve it is difficult to see and impossible to reach with a pad. Back-purge properly and the problem does not arise; skip the purge and the inside of the bend is where the system starts to fail.\u003c\/p\u003e\u003ch2\u003eOrdering\u003c\/h2\u003e\u003cp\u003eOne bend per article.
