EVOLUTION EXHAUST SYSTEM for the YAMAHA YZF-R1 (2004 - 2006)

Supersport motorcycles like the Yamaha R1 call for top-quality aftermarket components, and the Akrapovic RACING / EVOLUTION systems definitely rank in that category. Installing one of these systems will make the engine come alive, with a huge 160.7 HP delivered to the rear wheel way up at 12730 rpm. Experienced riders and racers will be able to maximize the advantage offered by the Akrapovic RACING (stainless steel) and EVOLUTION (titanium) exhaust systems. In addition to the increased performance, the visual effect is also dramatic, as the systems fit right in to the sharp lines of the Yamaha. Both systems are also available in EC Type approval version.

Performance

Measurements of the Akrapovic EVOLUTION system on the YAMAHA YZF R1(without muffler inserts):

Power & Torque: Akrapovic RACING/EVOLUTION systems allow the Yamaha engine to breathe to its fullest, as can be seen in both the power and torque curves. In addition to increased power, the system levels the power curve into a linear contour. The power increase begins at the low end at 3400 rpm and lasts up to 4600 rpm. From there to 6200 rpm the Akrapovic curve follows the stock curve. From 6200 rpm on the curve shows the qualities characteristic of the top Akrapovic systems. The increase runs all the way to the top of the rpm range, where it reaches max. power of 160.7 HP at 12730 rpm. The max. increased power is a massive 7.9 HP at 7200 rpm. The torque curve is even more eye-opening, as the system exerts an even greater influence on the stock curve. The drop-outs in the stock curve at around 3600 rpm and 7200 rpm are filled. The engine will be responsive at every point, allowing both racing intensity and smooth shifting at low revs. You will also save up to 2.81 kg compared to the stock exhaust system.
