Here's a bit of random question... are finned exhaust clamps necessary? I've been running my BSA A10 without any for a few months now (I forgot to fit them when I installed new 2-into-1 exhausts). I'm just wondering whether they are purely aesthetic? or do they have a useful function?
I assume they assist with cooling the exhaust but, depending on the size of the fins; I'm a bit doubtful that they'd have a significant effect. What do you reckon? Thanks guys!
