AKRAPOVIC Slip-On Line Muffler - Titanium - Black - BMW R 1300 GS S-B13SO4-HJGTBL

If you're riding a BMW R 1300 GS, you already know that weight savings and genuine performance gains matter. The Akrapović Slip-On Line Muffler delivers both—a titanium construction that cuts nearly 10% off your stock exhaust weight while adding measurable power at the crank and a deeper, more refined engine note. Best of all, it's a bolt-on installation with no ECU remapping required, making this one of the most straightforward upgrades to unlock your boxer engine's potential.

Developed through years of Akrapović's proven work with the BMW GS platform, this double-flow muffler combines lightweight titanium with a handcrafted carbon-fiber end cap to achieve real-world performance gains without compromise. The specially profiled muffler surface strengthens the design while reducing environmental impact through superior sound silencing—proof that you don't sacrifice acoustic character for responsibility.
