The assembly can be clocked on the motorcycle, taped, ridden with, and only then committed — or never committed at all, if springs are doing the holding.\u003c\/p\u003e\u003cp\u003eThat is a different way of building an exhaust from cutting and welding, and it suits a project that is still finding its shape.\u003c\/p\u003e\u003ch2\u003eWhere the Angle Fits\u003c\/h2\u003e\u003cp\u003eForty-five degrees is the corner most road systems are made of. It clears an obstacle without the flow penalty of a right angle, and it halves with a saw when the run turns out to need less. Between this article and a length of fifty millimetre pipe, most of a serviceable system already exists.\u003c\/p\u003e\u003ch2\u003eRepairing Rather Than Rebuilding\u003c\/h2\u003e\u003cp\u003eThe practical value of a female corner shows up after the system is finished. A run that fouls under load, a silencer that has to move for a new pannier rack, a joint that has been cut apart for a weld repair — all of them are adjustments rather than rebuilds when the corners come apart.\u003c\/p\u003e\u003ch2\u003eRetention\u003c\/h2\u003e\u003cp\u003eTwo springs at opposing sides. Spark sells the springs in two lengths, with or without rubber, and the hooks that fit them in stainless or titanium. A band clamp will hold the joint too and will fight the thermal movement the spring is there to allow.\u003c\/p\u003e\u003ch2\u003eKeeping the Gap Dry\u003c\/h2\u003e\u003cp\u003eEvery slip joint is a crevice, and on a road machine the crevice corrodes before the exposed surface does. Exhaust paste on assembly, and a joint arranged so it drains downward rather than holding water, handles it. Do not seal a joint that has to slide.\u003c\/p\u003e\u003ch2\u003eOrdering\u003c\/h2\u003e\u003cp\u003eOne bend per article.
