I put a set of Hardly pipes on my CX. Used the one from a Sportster that a buddy of mine gave to me for free. They are louder than the stock pipes, but not overly loud. I had tried various things to get the holes in my stock mufflers covered to pass inspection. Foil furnace tape along with some wire was good enough to pass-the fix "blew" apart just as I was leaving the inspection station! But she got passed for her to get licensed! The welded fix may not be working, but possibly brazing some thin sheet metal over the holes and painting/powder coating may be the trick. Got any close up pics of the damage for us to look at?
