Akrapovic Titanium Slip-On for the BMW R 1300 GS

The Akrapovic Slip-On Line exhaust is developed exclusively for the BMW R 1300 GS and its new generation boxer engine. Constructed from lightweight titanium and capped with a handmade carbon-fiber end cap, this double-flow muffler is designed to reduce weight by 9.3% compared to the factory stock unit. Engineered to deliver a deeper, fuller exhaust note while maintaining EC/ECE-type approval, it features a specially profiled surface that adds structural durability and is finished with an engraved Akrapovic logo.

This exhaust system provides a direct bolt-on performance increase, yielding measurable gains in both horsepower and torque across the RPM range. It installs cleanly onto the factory header and maintains full clearance and compatibility with BMW Motorrad factory side cases.

Features:

• Performance Gains: Increases output by +1.9 hp at 7,600 rpm and +3.3 lb-ft of torque at 2,300 rpm.

• Weight Reduction: Titanium and carbon-fiber construction provides a 9.3% weight savings (roughly 0.5 lbs) over the OEM muffler.

• Premium Materials: Built with a lightweight titanium muffler sleeve and finished with a handmade carbon-fiber end cap.

• Luggage Compatible: Fully compatible with BMW Motorrad original side cases and luggage racks.

• Plug-and-Play: EC/ECE-type approved. Requires no ECU remapping or additional tuning for safe operation.

Fitment Notes:

• Preventing Burn-In: Before starting the motorcycle for the first time after installation, thoroughly clean the titanium muffler and carbon-fiber end cap with a contact cleaner or a mild degreaser (like WD-40 on a soft microfiber cloth). The oils and sweat from your bare hands during installation will instantly burn into the titanium finish once the exhaust gets hot, leaving permanent discolored fingerprints.

• Exhaust Valve Integration: Because this is a slip-on system, your BMW's factory exhaust flapper valve (located in the header/mid-pipe section) remains intact and fully functional. This ensures your low-end torque characteristics remain smooth and the motorcycle complies with factory idle noise regulations, while still opening up for a richer tone under heavy acceleration.
