Akrapovic exhausts street legal carbon for Yamaha R1 04-06

Akrapovič exhaust systems are developed by the same team of engineers who work with championship-winning partner racing teams in MotoGP, WSBK and other categories. All products are tested in the company’s own labs using their own highly advanced dynamometers.

Akrapovič’s Slip-On Line is designed for recreational riders. These exhaust systems are easy to install and they replace stock mufflers. They will give you more power, more torque and less weight and consequently a smoother ride. Most versions are with EC type-approval. 

Slip-Ons represent the first step in the exhaust system tuning process, and they offer a great balance between price and performance. Change the nature of your bike by adding more power, improved performance, and the unique Akrapovič sound. Everything packed in stylishly designed Slip-On exhaust systems. The result of taking design very seriously is a beautifully crafted exhaust system with a carbon fibre muffler outer sleeve. Race-proven materials.

It’s not just about peak power—Akrapovič exhaust systems deliver increased performance throughout the entire rpm range. Increased power and torque result in a much smoother ride. All Akrapovič exhaust system measurements are made on our computer-controlled flowbenches.
