I thought Onan exhausts were 1.25," not 1.5." Is the description correct? Thanks!

My Onan 2500 measures 1.25” o.d. and this slides right on. FYI it doesn’t necessarily quiet the sound but changes the pitch to make it less annoying.

Is there a baffles in this muffler

No. It’s a resonator. There is a deadening of tone, but not really any quieter. Still glad I got it. It helps.
