Just made my self a homemade set of cans for my Blackbird 1100 XX Could not stand the sound of the stock cans, they sounded like an electric sewing machine, With quite a bit of fiddling, I now have a good deep burble that above 4-5000 RPM quietens down and is not annoying when on a long run. Yes, I am a tight arse and not about to pay $1000 approx for a bought pair, Mine cost me about fifty bucks not including labour. Very pleased and happy with the result, and they are not a cop magnet either, I dont have any good polishing gear so that will have to wait untill I get some, Added bonus, they are smaller than the stock cans and tuck in more, so I dont have the black marks from boots on the cans anymore. For some reason I cant upload the piccys of them, I will try another time. Cheers, Brian.
