Yes, it's been done before...but not like this. Our improved flow version of the B11 colostomy bag replacement. Use on stock or aftermarket muffler. Guaranteed crack-proof. For stock or PC-V/AutoTune-200 users, purchase the single 02-sensor version (if a stock bike), or dual 02-sensor version if intending on using a PC-V with AutoTune-300, seen HERE.
