The Akrapovic E-B13E1 Header Pipe is designed for the BMW R 1300 GS and built for closed-course competition use only. Constructed from high-grade titanium and paired with a carbon-fiber heatshield, this header pipe reduces weight while improving exhaust gas flow. Its larger-diameter tubing and catalytic-converter removal help optimize the system for racing applications, delivering enhanced performance compared with the standard stock exhaust system.
A pre-muffler produces a deep, distinctive racing tone from the BMW boxer engine. The complete upgrade provides a 54.84% weight reduction, equal to 7.5 lb, compared with the standard stock system. When combined with the Akrapovic Slip-On Line (Titanium), the system produced gains of up to 4.2 horsepower at 7,800 rpm and 4.4 lb-ft of torque at 3,000 rpm on an Akrapovic dyno-tested BMW R 1300 GS.
Installation is designed to be plug-and-play for compatible applications, but engine remapping is mandatory after installation. The Akrapovic E-B13E1 is intended exclusively for closed-course competition circuits and is not designed for public-road use. Confirm vehicle compatibility and applicable competition requirements before installation.
