Got a Protti exhaust on my engine - advert at CASA does say that the carbon silencer won't last as long as a aluminium end can - more suited to race rather than road use. Anyhoo, I have noticed that the silencer is starting to come loose at the rivets already. What is the best way to repair these? Just re-rivet? Or is there a better way to make it last a bit longer?
Many thanks!
Re-rivetting end can?

Instead of standard rivets (aluminium), I always use stainless rivets, but gas tight:

They should last much longer.

As it warns on the advert that they aren’t best for Road they probably won’t - I’d rather sort it then it’s done.Scooterdude wrote:If the can is not to old can they not exchange it?
