Our manifolds have the same thread each end and therefore do not fit the silencer supplied with the E. An easy fix is to purchase an inexpensive ASP 1.20 silencer body - Four Stroke Silencers

Flexible Extensions

Flexible Extensions




Male/Male flexible exhaust extensions for OS and OS copies. These offer a great solution to mount the silencer in a position of your choice.




Notes about flexible extensions:

We do not recommend the flexi is screwed directly into the cylinder head. It is better to use a solid header or knuckle first.

Do not bend the flexi too tightly. We recommend a minimum of 50mm (2”) diameter.
Ensure joints are kept tight if required a few wraps of plumbers PTFE tape can be used.

We recommend you support the silencer; do not leave it hanging. If you have a problem with engine vibration mount the silencer support to the engine mount.

When mounting do not twist the flexi as this can cause the pipe to fail.
