“Silencer” or “Muffler” for 1970 DT1C

Hello All,    

I recently finished a restoration on my 1970 DT1C.  One of the things a enjoy about the bike is that wonderful sound only a 2-stroke Enduro can make.  Unfortunately my neighbors do not feel the same way : ).  Has anyone tried to reduce the dBs a bit by using an after market “muffler” or “silencer” on their stock exhaust?

Thanks!

Maybe the spark arrestor has been removed.. Might be able to attach an aftermarket effective tail pipe muffler with spark arrestor as part of it. I have something homemade & not pretty but is affective.

Man that's Uuuugggly lol.
Often the problen is resonating through the thin walls too. I was always going to get some wrap like i've see in adverts--with stuff--to wrap the complete system to deaden the resonating. Just make even uglier--but!!
Had an RD350LC complete exhaust on my RT1-360 to ride to work & was almost silent, heavy walls & thick header compared to the trail pipe. The days before digital cameras unfortunately.
