KANECJDL Exhaust Header Pipe for Predator 420 / GX Engines – Easy Install

Upgrade your Predator and GX engines with a durable exhaust header

The KANECJDL exhaust header pipe is designed to replace worn components on Predator 420 based models and select Honda GX variants. It covers Predator 420 parts as well as 301cc 8hp and 420cc 13hp configurations, and is compatible with GX240, GX270, and GX390 engines. This makes it a versatile choice for compact machines like mini bikes, go karts, golf carts, mud boats, and lawn equipment, helping you keep projects moving with fewer interruptions.

Crafted to perform under demanding use, the header features a robust weld and a protective finish. A high temperature coating helps resist heat and corrosion, so the part stays reliable even after extended runs and harsh environments. The welds are balanced for strength and flexibility, supporting a long service life through repeated heat cycles and vibrations common in off road and yard work.
