The JBA Y-pipe for 2003–2004 Toyota Tundra 4.7L opens exhaust flow to boost power and refine exhaust tone, serving as a direct mid-pipe companion to stainless headers. It’s hand-polished to a mirror finish for a custom look. Made from mandrel-bent 409 series stainless with O2 sensor provisions, factory-style hangers and heavy-duty flanges. Note: not legal for street use in California or states that follow California emissions.
