Richie I ordered my first set in chrome after about a week and half on the bike both pipes turned yellow all the way down the pipes and started to blue BAD! Was very displeased with them, called the co. I bought them thru and told me to speak to CFR owner Cary Faas, gave me his number. After speaking to him back in July he was shocked that retailers were selling his pipes and saying they are slip on's with no tuner required. he said regardless of mods on the bike that the pipes would require a tuner to prevent the bike running lean and discoloring the pipes. thier open flow thru design makes them diff. to tune but that is on any open pipe, very little back pressure. The trade off to that is a diff. sound, louder note that sounds like nothing else
