## Questions & Answers

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

**Q: Is there a baffles in this muffler**
A: No. It’s a resonator.  There is a deadening of tone, but not really any quieter.  Still glad I got it.  It helps.
