Has anyone added aftermarket exhaust to the GTL yet? What exhaust has been added. I was thinking about a Remus. Has anyone heard a Remus on the GTL yet? I had a Staintune on my R12RT and liked that a lot but I do realize that the GTL will sound much different than the RT (and better I hope). I do appreciate everyone's thoughts on the subject to help me make a decision. Thanks in advance!
