No not really. For one I still have the stock mid pipe (2 cats and 1 resonator) and Two look at most of the aftermarket exhausts how many of them have baffles in them how many are straight through? Almost all of our aftermarket exhaust are straight through and just change the tone or pitch of the exhaust. Also why would Nitto make a mid pipe that has no cats and 3 resonators for more straight through flow and would also have less back pressure?
