Two of these tension springs are used per exhaust installation, providing the clamping force that holds the silencer firmly against the pipe connection under racing conditions. A broken or fatigued tension spring allows the silencer to vibrate loose from its mount, creating exhaust leaks and risking damage from the silencer contacting the chassis.\u003c\/p\u003e\n\u003cp\u003eFits: \u003cstrong\u003eRotax 125 Senior MAX EVO, Junior MAX EVO\u003c\/strong\u003e exhaust system.
