dozy taxi driver damage, makes me happy

so i park my zephyr on the pavement, parralel with the kerb, up agina lampost to which it is chained. I do this so it doesnt get knocked over.

what happens, bleedin blind taxi driver mounts frickin curb knocksit over,and then drives off. next day i comeout bikes on its side,

driver didnt know his passengers just left my house, but admits everything when i turn up and suggest i knock his merc over! no one thought anyone would ever give me money for it, how wrong.

happily the only damage is the can now torn of the collecter pipe, now my 550 sounds like sw17 motogp !

my question is has anyone here been pulled for excessively loud exhaust noise? ive passed several coppers who didnt even look at me (as i rapidly upchanged). i really like the noise it makes and i dont wanna fix it!

Will it pass an MoT like that ?

Went on a ride out with a guy who hada GSXR 600 with an underengine exhaust, that was the loudest pipe I have ever heard, thought he was going to come screaming past at 100mph when I heard him behind me, but he just pooted up at 40!!

He didnt seem to have that much trouble with the police, but he was always watching around him…

Would a hole like that loose any power? thinking about exhaust pulses here…
