I have a 93 ultra with a set of kerker slip on's on it, i want to remove the baffles and packing and install some new baffles. These do not appear to have a set screw and they are not just tack welded in like others ive seen. Inside the mufflers are cone shaped. I was just wondering if anyone has had any experience with ones like this? Just don't want to start cutting and mess it up.
