Where do you get your engine manifolds? We design and manufacture custom ones in fairly any shape, type or size. Like these ones for our French client who installs them on his famous yellow diesel machines. On the picture you see only a small part of the system. The full Y-piece does not only consists of this low backpressure manifold, but also contains two bended arms with integrated compensators and an ‘easy install’ matrass thermal insulation. Made in Holland!
