This exhaust extension compatible with Honda EU2200i, EU2000i, or EU1000i units allows for safe venting of exhaust fumes from an unoccupied enclosed area. The buyer will receive: A custom low profile exhaust to 1" ID tubing stub. The exhaust stub will need to be welded onto the generator's stock muffler. A mechanic/exhaust/muffler auto repair shop can typically perform the weld if you are not able. Illustrated instructions will be provided.
