Why does my 1914 model t touring have a damper in the exhaust pipe?
Are you sure it isn't a cut out?
It is flapper with a spring attached to the frame of the car
It's a exhaust cutout. Do a Google search "exhaust cutout mtfca". You will get all kinds of info on them.
should have a foot pedal on the floor so you can open it when you need BIG POWER to climb a hill
