Let’s talk about the tension on your muffler exhaust springs. Too little?---Too much? Although there several types of exhaust and muffler setups out there, I’ll limit this article to the most common and that is where the exhaust spring holds the exhaust male outlet pipe into the female socket on top of the Rotax stock muffler. If you don’t have a stock Rotax muffler, but do use springs, then this article will still have significance for you.

What happens if there is not enough tension on our exhaust springs? The muffler will have excessive vibration and pulsation from the exhaust and cause the exhaust tube to hammer in its female socket. This will cause cracks, broken out pieces and the chaffing will eat away the edges of the exhaust pipe and socket and too little tension will cause hot exhaust gas leaks that might impinge on your hoses or wiring.
