The systems are lighter compared to the stock exhaust system and feature exceptional production quality and increased engine performance combined with pure racing sound output.A combination of racing materials like titanium for the muffler outer sleeve give these exhaust systems a racing touch. Peak performance alone is not everything - Akrapovic exhaust systems deliver improved performance across the rev range. More power and torque make for a much more comfortable ride. All Akrapovic exhaust systems are tested on computer-controlled flow test benches. | Article: Akrapovic Slip-On Racing Line Titanium Exhaust System, silver | Article: Akrapovic Slip-On Racing Line Titanium Exhaust System, silver, silver
