Cummins Power Generation, manufacturer of Cummins Onan generator products, does not endorse the use of RV generator exhaust pipe extensions. Like all fuel burning devices, engine-driven generators emit carbon monoxide (CO) which, if not safely handled, can produce serious injury or death. Cummins Onan generators, in conjunction with RV OEM installed tailpipes, are designed to meet RVIA standards for safely handling exhaust gasses while minimizing noise and maximizing generator performance. Improper modifications to the exhaust components can result in unreasonable hazards to the vehicle occupants. Read more about Cummins Onan’s statement about RV generator exhaust extensions.
