After evaluating the stock exhaust layout it was easy to see that removing the rear mufflers would accomplish what we wanted. Our axle-back exhaust is made from a 304 stainless steel tube in the same diameter as the stock exhaust and with mandrel bends for unimpeded flow. It fits with the stock hangers and is clamped to the stock exhaust pipes once the mufflers are cut off. And the entire installation can be done in about an hour with the exhaust on the car.
