What mufflers????

I have a Contemporary at Nicks now and I stuck a bore scope (used for examining rifle bores) inside of my collectors and I do not have ANYTHING in mine.

WHAT DID YOU SAY??? I have taken to wearing small ear plugs during driving (26 dba reduction. available at Walmart) that I use to compliment my hearing protection while shooting. Stopped the ringing and you can still hear.
