⚬ Custom-made by Akrapovic, the world's leader in exhaust system technology. The use of titanium alloy results in a significant weight saving, better heat dissipation and improved flow characteristics. In addition to either carbon or titanium silencers, the PGMV8 comes supplied with a handmade MotoGP style system which delivers a howl reminiscent of a 1970's F1 V8.
