The MIVV de-catalyzed tube in stainless steel for Yamaha WR125R/X (manufacturer reference M.YA.026.C1) transforms the exhaust system by adding a distinctly racing look and a more pronounced sound character. Designed for cross/competition use, this de-catalyzed collector pairs particularly well with MIVV slip-on silencers while remaining compatible with most original exhausts.
Important: this tube is not approved for road use — reserved for tracks or off-road use according to local regulations. Installation may require adjustment checks (carburation or mapping) to ensure proper engine adaptation. For optimal installation and adjustment, consult a specialized workshop.
