Hope this clarifies things
Thank you, this is very productive information. For those interested in the one I ordered, this is quoted from the product description...
Flowmaster introduces its brand new Force II system for 2008-2011 Ford F250 Super Duty trucks with gas engines including the new 6.2L V8. This system provides the perfect balance between delivery of increased power, torque and mileage. The fully mandrel bent system consists of a clamp-on adapter that connects after the catalytic converter mounting a Flowmaster 50HD Series single inlet, dual outlet muffler.
Of course I will post back when I know for sure that it will work on our trucks, albeit maybe not a true “Catback” I do have faith...
