I honestly think that's where they developed their 4 stroke pipes from, that expansion chamber technology yielded results that were adaptable. Pure conjecture on my part, but it makes sense....Did you ever see the 2 stroke chambers they made , they were welded seamed , really quite neat , and worked really well on the RZ350 . That little bike was a giant killer in its day and that banshee wail was something else with those chambers fitted !!
