Melting Delkevic exhaust strap

I bought a Delkevic tri-oval exhaust a few months ago and think it looks and sounds great, the only problem i've had is just recently the rubber strap on the clamp that secures it has started to melt but only on one side of the exhaust (inside) has anyone else had this issue, searching on google i found a couple of occurences. my bike is running fine even had my mechanic mate give it a quick once over to ensure the exhaust wasn't getting excessively hot. I can't fault delkevic on their customer service though i emailed them yesterday about it and they've sent out a replacement strap today.

Not had a similar experience with mine perhaps just a dodgy strap. Hope it hasn't marked your can and the new one isn't the same.

Doesn't seem to have marked the can, i'll have a better look when the new strap arrives and i swap it over. I hasn't really melted onto the can just started to smoke quite bad and the rubber has started to fall to pieces.
