More Horsepower and Torque. Replace those heavy, restrictive cast iron stock exhaust manifolds with a set of Kooks Super Street Shorty Headers. This upgrade will increase the horsepower of your 5.0L Coyote Powered Mustang by approximately 10-12 horsepower. Additionally, these Kooks headers are approximately 50% lighter than stock.
Quality Construction. Kooks Super Street Shorty headers are manufactured from 1-7/8" mandrel bent 304 stainless steel tubing with 3" collectors for superior exhaust flow and optimal performance. These Kook shorty headers feature a one piece 3/8" header flanges that are TIG welded for extra strength and a direct OEM style fit.
Application. These Kooks Super Street Shorty Headers are designed to bolt straight up in the stock location to the stock Mid-Pipe without any modifications required on the 2011 to 2014 5.0L GT and BOSS Mustangs for improved exhaust flow and sound.
