Yoshimura Exhaust Spring | 3-Inch | Replacement Muffler and Header Spring

The Yoshimura Exhaust Spring is a 3-inch replacement spring for retaining exhaust joints on Yoshimura systems, holding the header-to-muffler and header-to-cylinder connections under constant tension.

Exhaust springs are the most overlooked component on a performance exhaust and the one most likely to strand a bike. They live in constant heat cycling and vibration, they stretch over time, and a spring that has lost tension lets the joint work loose — producing an exhaust leak, a rattle, and eventually a system hanging off the motorcycle. On an off-road machine they also simply get torn off by branches and crash damage.

This is the longest of Yoshimura's common spring lengths, used where the joint span is greatest. Measure the spring you are replacing before ordering — a spring that is too long will not hold proper tension, and one that is too short will not reach.

A sensible spare for anyone running a Yoshimura exhaust on a motocross, enduro or track machine, where springs are lost and fatigued most often. Measure your existing spring to confirm the 3-inch length before ordering, and use a proper exhaust spring puller when fitting.
