[DT175MX replacement silencer]

I have looked inside my existing silencer and it is full of wadding. Is the big boy silencer better for silencing that sharp crackle from the tail pipe?

My DT175MX has a small ally silencer that is stuffed with fibreglass but the noise from the exhaust is to loud so maybe a big boy would be quieter, can any one give advice please. Also the Dt is 4 stroking at low throttle with a lack of power until increasing the throttle. Could this be the needle setting??

[DT175MX 1982 improve silencing]

Hello Yamaha DT175 friends. Can the small silencer on my 1982MX be dismantled and more sound muffling put inside? At the age of 74 and living in a quiet area it would be nice to reduce the sharp crackle. Any suggestions please. CRJ
