Installation Notes

Confirm the pipe diameter and flange style before installation so the gasket matches the exhaust connection. Clean mating surfaces thoroughly, inspect the flange for warping or corrosion, and align the exhaust components before tightening to help achieve an even seal. For fitment-specific service, verify the vehicle application and position, such as the RX350 rear converter to muffler assembly or Colorado front converter to rear converter, before ordering Walker 31555.
