Is your B&B a long-wheelbase model? It looks like you've got a 94" chassis there. If you extend the length between the sidepipe cutout and the rear of the door, you have to extend the sidepipes to match. Your options are to use the longish collector tubes you have or a longer muffler housing. Anything more standard will leave the sidepipe exit somewhere under the door, a dorky, off-sized look.
