Constructed from premium-quality stainless steel, this exhaust has a lightweight titanium muffler outer sleeve and is beautifully completed with a handmade carbon-fibre end cap. It is refined and sporty looking, with a black coating and an engraved Akrapovi? logo within an all-new relief imprint, all designed to provide a classy and eye-catching finish. It reduces weight by over 38% from the stock system, improving handling on all terrains. The deeper, sportier Akrapovi? tone is seamlessly matched to the torquey twin-cylinder engine. It is easy to fit, with no remapping needed, EC- and ECE-compliant, and fully compatible with BMW's side cases.
