Im getting a 2010 GT500 soon, this model year is new to me as far as exhaust goes. Most options for aftermarket exhaust for this model year are for Axle-Back systems. Does this mean that after the pipe bend over the axle you run stock pipes to the mid-pipe? Does that cause any flow issues? If you run an aftermarket mid pipe are you going from aftermarket mufflers to a stock pipe to a aftermarket mid-pipe?
