Champion Generator #80 flange generator exhaust extension allows for safe venting of exhaust fumes from an unoccupied enclosed area. This is designed for units that have two-hole spark arrester cover plate #80. To verify this is the correct kit, please ensure the screen cover has 'NO 80' 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 gasket, and the specified length of 1-1/2 I.D. flexible galvanized exhaust pipe, and the proper size U-bolt clamp. The exhaust stub will need to be bolted onto the generator's stock muffler. Installation instructions will be provided. Thank you for looking!
