Description

The Kooks 1151H420 is a premium set of 1 7/8" x 3" T-304 stainless steel long tube headers designed to enhance the performance of your Ford Mustang GT or Dark Horse. Constructed from durable T-304 stainless steel, these headers are built to optimize exhaust scavenging, leading to increased power output. The kit includes 3" high-flow catted connection pipes, O2 extensions, gaskets, and all the necessary hardware for installation, ensuring a comprehensive solution. This product is specifically engineered for the 2015-2024 Ford Mustang GT and Dark Horse models equipped with the 5.0L 4V engine. Please be aware that these headers are not street legal in California and do not meet CARB compliance requirements. It is recommended to verify fitment manually as no specific fitment data was available for all 2015-2017 models. Additionally, due to high demand and supply chain delays, Kooks products may have an extended lead time of 8-10 weeks.
