The Kooks stainless steel 3" catted Y-pipe is a direct-fit OEM replacement for 2015+ Ford F-150 with the Coyote 5.0L 4V when used with Kooks headers. It accepts factory catalytic converters and is offered as a high-quality stainless exhaust component intended to work with Kooks header systems; standard race cats are not for use in forced-induction applications.
