The Ford Racing X-pipe for the 2015 Mustang GT converts the factory H-pipe to a more efficient X configuration to improve exhaust flow. Made from 409 stainless steel, the X-pipe clamps onto the factory system and requires cutting of the factory exhaust for installation with no welding required. It’s intended to reuse the stock catalytic converters and provide durable, long-lasting service.
