I remember back in my high milage sidecar days one of my mates had a 550f chop, he called it red rat - bin bag seat, dual sockett metal 240v plug housings with sponges in as air cleaner and a motad 4 into 1 setup, with the stock silencer cut / rotted off and replaced with a fergy tractor item - I'd bet he'd have knocked any baffles out. That thing used to belch flames out of the exhaust, but probably wasn't as loud as my sidecar with the bsm collector welded to a triumph rockett 3 (70s not modern) raygun silencer. Not sure if mine ever flamed but only with this exhaust and K&N filter could the bike ever wheelspin at will just by flicking the throttle. That sound does bring back memories. Motad stock silencers just didn't have that full on sound. Apparently, no pipes does.
