Use this to convert to true dual exhaust on a V6 car. The Mustang's oem cats are actually pretty good high flow cats. Rather than make you replace brand new ones, this specially made X pipe crossover can be added to your existing oem catted downpipe by cutting the downpipe in the appropriate spot and slipping this X-pipe over the existing pipes. OEM grade 409 Stainless construction. Clamp and instructions are provided.
