BMW fits an Akrapovic silencer to some R 1250 machines from the factory and sells the same unit through its accessory catalogue. Akrapovic states this header fits that silencer as well as its own aftermarket ones.\u003c\/p\u003e\n\u003cp\u003eIf your bike already wears the BMW-supplied Akrapovic can, the header alone completes the system — no second silencer purchase.\u003c\/p\u003e\n\u003ch2\u003ePlan for the Remap\u003c\/h2\u003e\n\u003cp\u003eAkrapovic recommends remapping the ECU when installing this header, specifically to prevent a check engine warning. That is a firmer statement than the usual performance advice: without it the dashboard is likely to complain.\u003c\/p\u003e\n\u003cp\u003eBudget a dyno session alongside the part rather than discovering the warning light afterwards.\u003c\/p\u003e\n\u003ch2\u003eStainless Steel, Not Titanium\u003c\/h2\u003e\n\u003cp\u003eAkrapovic builds two headers for this engine. E-B12E4\/1 is titanium; this one is stainless steel and costs more, which looks backwards until you see what it carries — the exhaust valve, the insert, and compatibility with BMW's own silencer.\u003c\/p\u003e\n\u003cp\u003eSteel is also the more forgiving material on a machine that sees winter roads and gravel.\u003c\/p\u003e\n\u003ch2\u003eWhich of the Two Headers to Buy\u003c\/h2\u003e\n\u003cp\u003eAkrapovic catalogues two headers for this engine, and the choice is not about performance — the published figures are close. It is about what else the part brings.\u003c\/p\u003e\n\u003cp\u003eTake E-B12E4\/1, the titanium one, if weight is the priority and you are buying an Akrapovic silencer to go with it. Take this stainless one if your motorcycle already wears the Akrapovic silencer BMW supplies, if you want the removable insert, or if the bike sees salt and gravel. Steel is heavier and more durable; titanium is lighter and more delicate. Neither is road legal.\u003c\/p\u003e\n\u003ch2\u003eThe Insert Is Not an Approval\u003c\/h2\u003e\n\u003cp\u003eThis header ships with a removable insert, which on a type-approved slip-on would be the part that keeps it legal. Here it is not: the header has no approval with the insert in or out. It changes the sound, nothing else.\u003c\/p\u003e\n\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\n\u003cp\u003eE-B12R7\/1 covers the BMW R 1250 GS, GS Adventure, R, RS and RT from model year 2019 through 2024.
