i was wondering if anybody had a complete yoshi exhaust on their 400ex?how was the fitment?was getting the jetting right pretty spot on,with the specs that yoshi gave with the exhaust?what over all performance gains?did the pipe take away ony bottom,top,or midrange? i live in north florida and i own a 2001 raptor. thanks for your time,yoshi doesn't have specs yet. if it helps to ward off any bashing, i have a 86 310r and a 99 400ex
