Hi all,

Just taken my micron exhaust can off my fzs600 and shone a torch down the link pipe and it shines right through to the exit of the can, it MOT time thats why its off. It doesn't have a db killer so is a fruity noise but i hadn't realised it was straight through.
My question is this, is this straight through can damaging the engine, something about back pressure? I know its illegal and thats my decision, but I don't want to ruin my engine.
Many thanks
Nick
