I have style A Flowmasters on mine. When I originally went to the exhaust shop for an estimate, I had style B mufflers purchased. My bender suggested I return them and get A. He said, and I agree, that the offset outlet would dump too far to the outside. He would have to bend back toward the center while going over the axle then straighten out in time to clear the gas tank. Fastcat, I would be interested in hearing your thoughts on style B's flexibility for adjustment.
