Upgrade the exhaust performance and sound of your BMW R 1300 GS with the Akrapovič Slip-On Line muffler, manufacturer part number and vendor part number S-B13SO4-HJGTBL. Developed specifically for the BMW R 1300 GS, this premium replacement muffler draws on Akrapovič’s extensive experience with BMW GS motorcycles and boxer engines. Its lightweight titanium construction and handmade black carbon-fiber end cap provide a weight saving of 9.3% compared with the standard stock exhaust while delivering a refined, durable finish.
The Akrapovič muffler features a double-flow design engineered to improve performance while maintaining effective sound silencing and reducing environmental impact. Riders can expect a deep, full exhaust note along with claimed gains of 1.9 horsepower at 7,600 rpm and 3.3 lb-ft of torque at 2,300 rpm. These performance figures were recorded during back-to-back Akrapovič dyno testing against a BMW R 1300 GS equipped with the standard stock exhaust. A specially profiled muffler surface adds strength and durability, while the engraved Akrapovič logo gives the system a distinctive, high-quality appearance.
Designed for straightforward installation, this BMW R 1300 GS exhaust muffler uses a simple plug-and-play fitment and does not require engine remapping. The system is EC/ECE type-approved for compliant road use in applicable markets and remains fully compatible with BMW Motorrad side cases after installation. This Akrapovič titanium slip-on muffler is an ideal choice for BMW R 1300 GS owners seeking enhanced exhaust character, proven performance improvements, premium materials, and dependable touring compatibility without replacing the complete exhaust system.
