OK, I've never seen the right side single out muffler listed in all the places that sell them.
I have a single left side out B&B and they're made well but mine is heavy and was quite restrictive to exhaust flow until I removed all of the internal baffles and flow directors and opened up where it closes down to 2.5" ID to 3" with a die grinder.
I left the approximately 3/4" of stainless steel packing that surrounds the sides of the interior and it sounds really nice now. Not too loud and you can hear a little turbo whistle. Feels like around 20 more horsepower too.
