Just a cautionary note on judging your new sound. I installed a RLS cat delete on my 2020RT, without the baffle. It is slightly louder than before, but isn't objectionable. Lost some fuel mileage. The caution is to evaluate the sound while riding and not when you rev the engine while standing still. Mine is a little throatier when riding and that's fine. If I rev it while stationary, it sounds like one of the hopped up rice-burner cars -- tinny and awful.
