The Borla Touring Cat-Back system for 2007–2021 Toyota Tundra (4.6L/5.7L) is a True Dual cat-back exhaust with 2.25" diameter piping and split side exit featuring 4" black chrome tips. Constructed from T‑304 stainless steel with mandrel bends, it uses an internal H‑Pipe for improved sound and flow, yields a mellow Touring tone with no in-cabin drone, and is lighter than the factory system while improving exhaust flow.
