Here is an original tipped up silencer that Steve Madden gave me a few years ago. I've just cut the end caps off to expose the baffles. There's nothing in the middle. Ron
Ron...The left hand half of that baffle has an additional piece fitted in the end....Could you show that 'end on' or from an angle to show the detail of that part more clearly?....Ian
This to add to my previous pictures.
The dimensions are as follows:- OD of rear tube = 1 13/16" (46mm) length of tail pipe = 3" (76mm) length of baffle = 6 1/2" (165mm)
The front pipe is 2" (50mm) OD and the bit that is squashed like a reed valve is 3 1/4" (82.5mm) long. Ron
Overlander already make M20 mufflers in stainless and Barry will put any baffle you like in there

Make you a matching M20 exhaust pipe in stainless as well.
