Maybe It sounds worse because the holes in the exhaust got bigger ?

the silencer has been weld up before so it my be falling apart. i think to save money i will use ear plugs and forget about it.

I know when the collector box on mine looked like this

it ran like crap at low revs but went a little better flat out
A fresh set of plugs may help it a little
