hi please could someone tell me is there any company out there who does replacment exhausts for my 97 cb 750. i have just purchesed this bike and am over the moon with it but sometime in the past the left hand silencer has been scraped and would like to no if its possible to cut the pipe and fit end cans on this bike as it appears to have no seperate end cans.i would also like if possible to just increase the decibels as it is a tad too quiet for me.possibly dimensions of the front pipes would help as well thanks les
