Heres a good question..........who has done the most miles with their performace back box fitted??
Reason I ask?? Well.........I'd love to know what the sound difference is between a fresh one and one that is well coked up with soot.
Other reason..........I wonder if its possible to clean them out
with our kart.......you could remove the exhaust......take the wadding out......and the baffle.......seal up one end (rubber glove and jubilee clip) fill it with old petrol and a can full of washed pea shingle, seal the other end........and then shake it like mad for about 5 minutes on and off
. Take the seals off, drop the crap into a bucket for disposal, put the wadding back in.....and the baffle.......cap on end......and voila.....one new quieter exhaust
I wonder if its possible to do something similar with the ZS after a year or so??
