3" x 2-3/4" Catted H-Pipe

The Kooks 11413500 is a performance-oriented, catted H-pipe engineered specifically for the 2011-2014 Ford Mustang GT 5.0L 4V. Constructed from durable 16-gauge 304 stainless steel, this H-pipe features a 3-inch diameter with a 2-3/4-inch outlet designed to mate with the OEM exhaust system. It incorporates Kooks Standard 300 Cell High Flow Catalytic Converters for improved exhaust flow and sound while maintaining emissions compliance. The connection to the headers utilizes a ball and socket style, and it must be used in conjunction with Kooks Headers featuring 3-inch collectors. This H-pipe includes necessary clamps for installation. Note that the 2-3/4-inch outlet is intended to reuse the factory exhaust clamps, which are not supplied with the product. Kooks advises that their Standard catalytic converters are not recommended for use with forced induction applications. Built to order in North Carolina, please anticipate an estimated ship window of 4-6 weeks. For urgent needs, Kooks suggests contacting them directly or locating an authorized dealer with available inventory.
