The JBA Y-pipe for 2005–2006 Toyota Tundra 4.7L is an emissions-legal mid-pipe option designed to open exhaust flow for improved sound and responsiveness while pairing with stainless headers. It’s hand-polished for a mirror-like appearance. Made from mandrel-bent 409 series stainless with factory-style hangers, heavy-duty flanges and O2 sensor provisions. Note: features also state limits for use in California and states that follow its emissions rules.
