I have a set of python slip ons. I don't use them, but I did at one time. The sound was 'tinny' at best when I bought them. Very disappointed. I pulled the baffles out and welded in a set of Samson baffles of a larger diameter. Much louder, deeper sound. They are a good looking muffler, but had to be modified for a decent sound. They've been sitting in my garage for about 4 years now that I switched to a 2-1
Try Big City Thunder dot com(not sure if we can post links here). I have them and really like the sound difference it made on my Fat Boy with V & H twin slash slip-ons, it now has a much deeper sound, cool sound and not louder. I got the quiet baffles! !
couldnt agree more...Love the sound and power from these
