Based on the specs, the Onan 155-2325 exhaust tube kit should work with the Onan 0155-2449 exhaust resonator, as the 155-2325 tube is listed as a 1-1/4" O.D. tailpipe and the 0155-2449 resonator is designed to install over a 1-1/4" O.D. tailpipe.

Based on those measurements, I have purchased the resonator and the connections on that measure 1-1/4” OD and the pipe I already have off my generator appears to be the same as this exhaust tube kit measuring 1-1/4” OD. This setup does not work with the muffler/resonator as stated as the pipe will not fit in or over the resonator fitting.
