Four Stroke Silencers

Four Stroke Silencers

Silencers to fit O.S. and O.S. compatible engines (ASP, Magnum, SC, Thunder Tiger) as well as Saito.

We are constantly reviewing and increasing the number of silencer options we carry, particularly quiet silencers. We aim to offer the widest range of exhaust options including some realistic alternatives to going electric where noise is a serious issue.

Scroll down for Super Quiet silencers and the ASP 400 Jen Ring silencer.

Customer Feedback

"I am surprised and delighted again at the range and quality of service that your company provide. I never seem to come away empty handed or without my being satisfied on every occasion. Today I have purchased two silencers instead of one I required as a copy is available on your site at half the price of a branded item but I can see no reason why it will not do the job. Here?s hoping to do business with you again in the future." - Maurice
