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??

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
