Muffler signs are collected. That one I think is 80's early 90s. Definitely not 325, around $60-80 given condition would be averge. Cherry condition $100.

There are some pretty cool muffler signs out there, Walker is a good name that's been collected for a long time. The complete display stands w/mufflers can run $300-600. One of the coolest I've had was a 3 sided display with a seal and then a rod through it holding a muffler that would spin around.



Collecting anything keeps you young at heart!
