Show original supplier description

The Ultimate Headers 473031 swap headers are engineered to simplify the installation of a Ford Coyote engine into older Mustang models. Crafted from robust 321 stainless steel tubing and featuring unique investment cast stainless steel flanges, these headers offer superior strength and longevity. The design incorporates tight radius cast stainless steel elbows, which facilitate the installation of large diameter tubing (1-7/8" with 18-gauge wall thickness) even in confined engine bays. This design also contributes to improved airflow. The headers come as a complete package, including mounting hardware, Cometic HTS gaskets, and O2 sensor ports. These headers are specifically designed for use with the 10R80 automatic transmission. Fitment also requires a tubular k-member. It is important to note that these headers are intended for closed-course competition use only and are not legal for street use. Their sale, use, or installation may be illegal nationwide under the Federal Clean Air Act. Additionally, the product warning includes information regarding California's Proposition 65, citing cancer and reproductive harm.
