    Product Information

    Akrapovic Evolution Line Full Exhaust for CRF250R 11 (Closeout)

    The Akrapovic Racing and Evolution complete exhaust systems are the championship winning flagships of our product lines. They are designed for competition-oriented MX riders who demand maximum performance from their exhaust systems, made of extremely durable high grade titanium. With their production quality, engine performance improvements, weight reduction and modern Hexagonal muffler design they satisfy even top pro racers. The systems are designed for two markets; in the USA they are available with an approved spark arrester, and for the EU and other non-US markets they come with a noise damper. Our patented additional chamber helps to reduce noise emission and provides better power and torque delivery. For the Racing system we use stainless steel tubes and composite end cap while we use titanium tubes and carbon-fiber end cap for the Evolution system.
    • Oval-shaped can wrapped in a titanium outer sleeve
    • Outlet cap, perforated inner sleeve and inlet cap are all constructed of high-performance titanium
    • Titanium-constructed conical-shaped header tube features a titanium-constructed flared or conical mid-pipe welded to the muffler
    • Link pipe: header tube joint is milled on a state-of-the-art CNC machine and secured by high-quality, silicon-shielded tempered springs
    • Features an included lightweight, compact and high-temperature resistant carbon-fiber muffler clamp
    • Prevention of seizing, corrosion and excessive wear of titanium parts due to vibration and extreme heat, is supplied by ceramic anti-seizing grease
