Akrapovic Evolution complete exhaust system no street legal with titanium pipes and carbon silencers for Yamaha R1 09-14

Akrapovič titanium Evolution systems are designed for riders that demand maximum performance from their motorcycle. The systems are significantly lighter compared to the stock exhaust system and feature exceptional production quality, hi-tech materials, and of course increased engine performance combined with pure racing sound output. Perfect welds and a combination of racing materials like carbon fibre.

 

Difference to our standard Evolution system: 

Headers with crossover

Headers with different layout for bigger race radiator

Link pipe without fixing points for stock heat shield

Mufflers without db killers

Heat shields on the mufflers are made for racing and you can’t fit stock one

 

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.
