Hi there, I just picked up a beautiful 78 SR500 and cant seem to find much aftermarket exhausts out there (actually, its bordering ZERO) Im looking for black head pipe and exhaust. My buddy has a sweet setup on HIS SR thats got the Supertrapp muffler and it sounds SWWWWWEEEEEEETTT. From what ive heard White bro.s stopped making the head pipes, so SUpertrapp stopped making the setup for the SR's ...so to my question: Does anyone have experience with this, if so what have you used? What work have you done to the Carbs? any bonus info is greatly appreciated. LOVE the site~!
