I've wanted one of these things forever. I'm soooo jealous, A riding buddy of mine just baught a "93" GSx1100G from Nashville craiglist today. The pictures show, what looks like Yoshimura nameplates on the stock exhaust. If I understood correctly, the seller told him the bike from the factory had the Yosh exhaust. My buddy said the nameplates did not look like they had been added, but looked original. Did these bikes come with Yosh exhaust, or did Yosh make slip'ons for these bikes? Also does anyone make a 4 into 1 for these bikes? He's not very excited about the sound of the 4 into 2, very different from the 4 into 1. Just feeling things out for him. He did get all the original parts, mirrors, turn signals, handlebars, but no trace of any other exhaust
