Good To Know

Q: Do I need to replace the gaskets and springs at the same time? A: Yes, worn gaskets leak and stretched springs let the pipe joints move, so replacing both together restores a proper seal.

Q: Is this kit a direct fit for the listed model years? A: It is designed to fit the 1985, 1986, and 1991 Polaris Indy 400 exhaust, though you should confirm the pipe configuration on your machine before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
