help identifying an exhaust rubber?

[Chrome4320]

right just a quick one guys, my dad's looking to spruce up our robin hoob 2b ready for the summer and we've noticed the exhaust silencer rubber mounting is not long for this world, any of you guys recognise it? it's a sierra base kit car so not sure if that points in the right direction? thanks in advance!
