Just Finished a new exhaust system for the NB cars.  This will be the best flow path of any dual exhaust for the NB miata.  The 3" midpipe mates to the BEGi downpipe then turns toward the Center of the car eliminating the 150 degree bend to make the transition to the dual mufflers.    Each muffler handles 1/2 of the flow in an incredibly balanced system.    It sounds badass!
