Champion Generator #90 3-hole or 4-hole round generator exhaust extension allows for safe venting of exhaust fumes from an unoccupied enclosed area. This is designed for units that have three-hole spark arrester cover plate # 90 and also for round spark arresters with 4-holes. To verify this is the correct kit for the 3-hole version, please insure the screen cover has 'NO 90’ stamped on it.

The buyer will receive: a custom low profile stainless steel exhaust stub with a male 1" NPT thread, 1" NPT to 1-1/2" adapter, longer replacement screws, and a high temperature stainless foil graphite gasket.

The exhaust stub will need to be bolted onto the generator's stock muffler. The existing spark arrester and flange will need to be removed. Installation instructions will be provided.


Custom hose size/length and exhaust stubs are available.
