SLIP-ON EXHAUST SYSTEM
HONDA CRF 250R (2008)
The Akrapovic Slip-On system is designed for recreational riders. It delivers an
excellent combination of quality, performance, visual enhancement, easy installation and affordability. The Akrapovic Slip-On is designed for two markets;
in the US it is available with an approved spark arrester, and for the EU and
other non-US markets it comes with a noise damper.
PERFORMANCE
Measurements of the Akrapovic SLIP-ON system on the HONDA CRF 250R
(with muffler inserts):
Power & Torque: the engine reacts to the change of the exhaust system by increasing the value of power and torque, which is noticeable through entire rpm range. We
measured max. power increase of 1.3 HP at 6600 rpm.
CONFIGURATION
The twin-pipe Akrapovic SLIP-ON system for the Honda CRF is composed of titanium
mufflers and exceptionally short cylindrical stainless steel link pipes, which are welded to the mufflers. At the other end the link pipes are attached to the header assembly
using sleeve joints held together with metal clamps and silicon-shielded springs. The
mufflers are attached to the frame using Akrapovic offroad carbon-fiber clamps. The
mufflers are available with titanium outer sleeves, with titanium outlet caps, while the
inlet caps and perforated inner sleeves are made of stainless steel. The mufflers have
noise dampers for the European and other non-American markets, while for the US
market they are equipped with spark arresters.
