Description

The Kooks Custom Headers 11413200 is a high-flow, catted X-pipe engineered to enhance the exhaust system of the 2011-2014 Ford Mustang GT equipped with the 5.0L 4V engine. Constructed from durable 16-gauge 304 stainless steel, this X-pipe features a 3-inch inlet and a 2-3/4-inch outlet designed to connect to the factory exhaust system, reusing the OEM clamps. It incorporates Kooks Standard 300 Cell High Flow Catalytic Converters for improved exhaust flow while maintaining emissions compliance in 49 states. The connection to Kooks headers utilizes a ball and socket style for a secure fit. This X-pipe must be used in conjunction with Kooks Headers that feature 3-inch collectors. While clamps are included, the OEM exhaust clamps for the 2-3/4-inch outlet are not. It is important to note that Kooks Standard Catalytic Converters are not recommended for use with forced induction applications. This product is built to order in North Carolina with an estimated ship window of 4-6 weeks.
