This silencer can only be installed with the Doma header.

Developed on a dyno and tested on track, these 4-stroke silencers for twin-pipe systems on WEDIRT chassis with Honda CRF 450 engine (23-25) offer better performance than stock. Designed for competition, they meet the highest rider expectations.

Doma exhausts are globally recognized for their power and efficiency, trusted by top riders like Adrien Van Beveren, Maxime Renaux, Milko Potisek, Arnaud Demeester, Jorge Prado Garcia, Conrad Mewse, Josiah Natze, Tom Pagès, and quad champions such as Romain Couprie, Matthieu Ternynck, Randy Naveaux, Alexandre Giroud, Jeremie Warnia, Davino Bruneel, Kevin Saar, and Marc de Vries — as well as many SSV racers.

Made in France at our Calais (62100) workshops, Doma exhausts are for competition use only and not approved for road use.
