Is the motorcyclemods.com one DOT approved? The only thing I see is the option saying "lternate color Lens for Oblong Cateye - may be banned in certain jurisdictions; check local laws. - specify, smoke or clear "
I like a big block type burble, not just "insanely loud because I'm cool" exhaust. Center stand retention is a must as well.
Mark's does sound pretty sweet after listening to it again!
