This part replaces the pipes between the cylinder head and the silencer, including the catalytic converter, and it only works if a suitable silencer is already fitted — an Akrapovic slip-on, or the first-fit Akrapovic unit BMW supplies on some versions.\u003c\/p\u003e\n\u003cp\u003eOn its own it is not a complete exhaust. Ordered together with a slip-on it turns that slip-on into a full system, which is where the 12.8 Nm comes from: a slip-on alone can only work on the last section of the path, a header opens the whole of it.\u003c\/p\u003e\n\u003ch2\u003eThree Hours on the Bench\u003c\/h2\u003e\n\u003cp\u003eAkrapovic quotes 180 minutes, the longest installation figure in this catalogue. The reason is what has to come apart: on an S 1000 XR the fairing, the radiator mounting and part of the cooling system are in the way before the header flanges are reachable, and the standard assembly comes out in pieces.\u003c\/p\u003e\n\u003cp\u003eThis is a workshop job with the bike on a lift. Budget the time or have it fitted.\u003c\/p\u003e\n\u003ch2\u003eRemapping Is Not Optional Here\u003c\/h2\u003e\n\u003cp\u003eAkrapovic states plainly that ECU remapping is mandatory for correct performance, throttle response and durability. Removing the catalytic converter changes what the lambda sensors see, and running the engine on the standard map afterwards is neither good for the numbers nor for the engine.\u003c\/p\u003e\n\u003cp\u003eBudget for the remap alongside the part. A header fitted without one is a header working against the motorcycle.\u003c\/p\u003e\n\u003ch2\u003eS and M Take the Same Header\u003c\/h2\u003e\n\u003cp\u003eBMW's M badge on the 1000 R and 1000 XR brings carbon wheels, a different suspension package and more electronics, but the engine architecture and the exhaust route are shared with the S versions. One header covers all four.\u003c\/p\u003e\n\u003cp\u003eWhat differs is the starting point. An M 1000 R already makes more than an S 1000 R, so the measured 6.8 PS quoted here — taken on the S — should be read as the character of the change rather than a guarantee for every variant.\u003c\/p\u003e\n\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\n\u003cp\u003eE-B10E5 covers the BMW S 1000 R and S 1000 XR from model year 2015 through 2020, and the M 1000 R and M 1000 XR.
