Description
Stainless steel flange kit for self-welding of the exhaust manifold for 28mm internal diameter.
The flange is symmetric, the bolts have a distance of 46mm and M8 thread.
It matches the original Dax/Monkey junctions mounting studs for the exhaust.
NHRC exhausts have a bottle neck with less then 23mm at the exhaust inlet.
The kit widens this bottle neck up to a continuous diameter of 28mm.
The measure improves the mass flow and performance for engines above 125cc significantly.
It can also be used as a base for a self-made manifold.
The kit consists of a piece of pipe, a ring and a flange with holes for M8.
Important Note:
The original bottle neck must be removed and the kit welded onto instead.
If you want us to do this work for you, please order it under P585.
