Hurt my eyes too...........

there loads of these in Japan for sale so they must have been popular at one time.

I remember Piper did a 3 into 1 for the Suzuki triples back in the day.

Sorry about that i dident check it before i posted it these andrid phones are crap online.i have seen some 2into1 pipes on banchees and rd350,s but never on a tandum twinn is it because the header pipes would need to be about 400mm long before they merge not sure how well that would work
