4-stroke collectors for double line DOMA YFZ 450 R with YZF 450 engine (2023 to 2025)

Developed on a power bench and on the track, this 4-stroke manifold for double line LAEGERS (Yamaha) YZF450 engine (2023-2025) and for original chassis YFZ450R with LAEGERS YZF450 engine kit (2023-2025) offers improved performance compared to the original one. With its improved bending and optimized tube diameter, it evacuates gases much more efficiently than the original one. This manifold is entirely made of high-end stainless steel and can only be installed on the corresponding Doma silencer for your quad.

Internationally recognized for performance and power, the Doma exhaust range has won over many quad riders such as Romain Couprie, Matthieu Ternynck, Randy Naveaux, Alexandre Giroud, Jeremie Warnia, Davino Bruneel, Kevin Saar, Marc de Vries

Doma exhausts are manufactured in France, in the workshops located in Calais (62100). They are only intended for competition use and are not homologated for road use.
