oad

Program

Like the Akrapovic dual muffler RACING and EVOLUTION versions, the single muffler RACING and EVOLUTION system is designed for riders who know who to take full advantage of the specific performance benefits offered by these systems. We should especially mention the new Akrapovic HEXAGONAL de-sign muffler, which with its carbon-fiber outlet cap goes exceptionally well with the design of the Honda.The muffler has a noise damper for the EU and other non-American markets, and a mandatory spark arrester for the American market.

PERFORMANCE

Measurements of the Akrapovic EVOLUTION system on the HONDA CRF 250R (without muffler insert):

Power & Torque: the single muffler version delivers a perfomance increase mainly in the middle of the rpm range and at the top end and overrev. Good riders will know how to make the most of the advantage.

CONFIGURATION

The Akrapovic Evolution system uses titanium tubing and the Akrapovic Racing uses stainless steel tubing. The tubes for the header assembly are flared to provide im-proved exhaust gas flow, while the link pipe is conical. The systems’ individual com-ponents ‡ header tube and link pipe – are attached using a sleeve joint held together with a silicon-shielded spring. The link pipe is welded to the muffler.

This system, unlike the stock system, has just a single muffler. It features a HEX-AGONAL design muffler, which goes exceptionally well with the design of the Honda. The muffler have in case of Evolution titanium inlet cap and perforated inner sleeve, in case of Racing stainless steel inlet cap and perforated inner sleeve. The outlet cap is made of carbon-fiber. The outer sleeve is made of titanium for the Racing version. For the Evolution both options of the outer sleeve are available ‡ carbon-fiber and titanium. The muffler is attached to the frame using an Akrapovic offroad carbon-fiber clamp. Evolution system also includes a carbon-fiber heat shield.The muffler has a noise damper for the EU and other non-American markets, and a mandatory spark arrester for the American market.

Technical specifications of Akrapovic exhaust systems and related products subject to change without notice.
