I have the urge to re-pack the silencer on my 2003 315R. I haven't taken anything apart yet but looking at the silencer it seems to be riveted. Will it naturally come apart if I dismantle the exhaust or do I need to drill rivets out?

Yup....drill them out, remove all the minging slop and snot from inside, give it a real good scrub out with something like GUNK, then repack using loft insulation such as ROCKWOOL. New rivets to complete the job. Nice. (Don't do it on the wife's carpet though!)

i have just repacked my 98 cota as i thought it would make it more pleasurable to the ears, however i havent noticed any difference , let us know how it goes and if it makes a difference

cheers

Fill the exhaust but don't ram it in solid.

Just poke it in firmly, if it's rammed in tight it won't quieten it down as good.!!

try rockwool out of your attic

it's cheaper than buying the proper gear from a bike shop!! but get your gloves on and don't rub your eyes!!

Really

As this is an old thread is this advice still good or is there a better cheap packing now?

Only because I had some in my workshop.

I have succesfully used fibreglass tissue in my 1978 Cota 348 exhaust.

This is the fine stuff that you use to tidy up chopped strand when mould making.
