A premium stainless side-exit cat-back from Kooks, a brand best known for headers, for 2015-2020 5.0L F-150s -- routes both pipes out one side with black-finished tips.
why this one — Kooks builds a matched cat-back for its own long-tube header customers, giving 5.0L owners a single-brand exhaust path from header collector to tailpipe.
Kooks' own product page for 13614110 could not be reached (kooksheaders.com/products/13614110 and /oem-x-3-cat-back3058 both returned 404 on 2026-07-26), so the manufacturer side is UNVERIFIED rather than confirmed-absent. Kooks elsewhere publishes only durability ratings (e.g. "rated up to 750rwhp"), which are not gain claims.
