Item(s) Info
Developed on a dyno and on the track, this 4-stroke header for the YAMAHA YFZR 450 (09-23) offers improved performance compared to the original. With its improved bend and optimized tube diameter, it evacuates gases much more efficiently than the original. This header is made entirely of high-quality stainless steel and can only be installed on the Doma muffler that matches your quad.
Worldwide recognized for its performance and power, the Doma exhaust range has won over a large number of quad riders, including Romain Couprie, Matthieu Ternynck, Randy Naveaux, Alexandre Giroud, Jeremie Warnia, Davino Bruneel, Kevin Saar, and Marc de Vries.
