OXA Factory GP Racing Edition exhaust RIEJU MR 300 i 2026

Take your 2026 Rieju MR 300i (Racing or Pro) to the absolute limit with the OXA Factory GP Racing Edition Exhaust. Specifically engineered to pair with Rieju’s groundbreaking new Throttle-Body Fuel Injection (TFI) engine and electronic exhaust valve, this premium, handcrafted expansion chamber is built for riders who demand crisp throttle response, unstoppable low-end grunt, and race-proven durability. Handcrafted in Spain by the enduro experts at OXA Factory—who boast over 25 years of competitive heritage—the GP Racing Edition features a raw, authentic factory finish that looks like it just rolled out of the paddock. Key Features & Performance Benefits Tuned for TFI Tech: Specifically optimized to complement Rieju’s 2026 twin-Bosch injector setup. It smooths out power delivery while offering an instantaneous, forceful snap right when you twist the throttle. Massive Low-to-Mid Gains: Gain the traction and torque you need to crawl up vertical rock steps, slick roots, and technical hard enduro climbs with ease. High-Ground-Clearance Design: OXA has tucked this pipe higher and tighter against the frame compared to the stock unit. This significantly reduces exposure to typical trail impacts, ensuring your header stays round instead of crushed. Handcrafted Craftsmanship: Every single pipe is meticulously welded and dyno-tested by hand in Europe to ensure precision fitment and maximum performance. Direct Bolt-On: Engineered for a flawless, modification-free fit. Comes complete with all the necessary seals and mounting hardware so you can spend less time in the garage and more time on the track.
