transmaster

When I first looked under my trick back in December is was snowing, blowing and in the teens temp wise so I did take much time looking around, At the time I could not spot the muffler. Now I see why. It is a bullet type glass pack that is just about the size you might find on a garden tractor, and is hardly any larger in diameter then the exhaust pipe, and about 24 inches long.
The exhaust system is in great shape so I don't have any reason to change anything right now but It would be fairly easy to cut out the glass pack and replace it with a flowmaster type muffler. The thing is except for the way the cab resonates at highway speeds the sound has grown on me.
