Description

Racing Line (Titanium)
The Akrapovic Racing Exhaust Systems with their titanium oval mufflers are top of the line products for this motorcycle. The increases in power and torque can be clearly seen from dyno measurements and felt while offroad riding. The muffler includes an approved spark arrester. The header pipe features an additional chamber for a better response at lower rpm and for more top end power. You will also save on weight, when compared to stock exhaust systems.and faster on the track.

Performance

The Akrapovic Racing systems provide the increased performance that top riders are looking for. Engine performance is increased throughout the entire rpm range. The power curve is steeper and smoother, and the increases are highest in the low end and top of rpm range. We measured max power output of 43.8 HP at 8001 rpm and max. power increase of 6.3 HP at 6780 rpm. The torque also gets a major boost, which will make riding smother
