Anyone tried to fit slip on pipes besides what is sold specifically for the Rocket3?

I recently spent $50 on a Triumph Thunderbird pipe. A few days with a grinder and a bit of welding and she's a slip-on to the unmodified stock headers.
It was more of an experiment to get ride off stock muffler to free up space for moving foot pegs backwards, but I like the sound and the lines are cool too, imo.
