This is included in new kits. This is the replacement downpipe that attaches the catifold to the muffler. Flange on one end, and 2" OD exhaust pipe on the other. The assembly consists of 2 mandrel bent 304 stainless bends and a 304 stainless 2" x 6" innerlock flex section. This is the most durable type of flex coupler available, and should last 15-30k miles. If the braiding on the outside of the flex is breaking apart, the flex will likely fail within the next 5k miles.
