JBA 05-06 Toyota Tundra 4.7L 409SS Emissions Legal Y-Pipe

The Y-pipe is a crucial part of your exhaust system, connecting the exhaust gases from your engine's manifolds or headers into a single pipe leading to the muffler. This JBA Y-pipe, constructed from mandrel-bent 409 Series stainless steel tubing, is designed to improve exhaust flow for your 2005-2006 Toyota Tundra with the 4.7L engine. Mandrel bending ensures the tubing maintains its diameter through the bends, which helps gases flow more freely than crush bends, potentially leading to a noticeable increase in performance and a deeper exhaust note.

This Y-pipe is built with heavy-duty flanges for a solid connection and includes factory-style hangers to ensure it mounts up correctly. It also features O2 sensor provisions where needed, making it a direct replacement for your stock Y-pipe. While it's designed to open up your exhaust system, please note that it is not legal for sale or use in California or states that follow California emissions regulations due to emissions compliance.

This Y-pipe can be a great addition if you're looking to enhance your Tundra's exhaust sound and performance. It's often paired with aftermarket headers to maximize exhaust flow improvements. JBA includes high-quality hardware and instructions to help ensure a professional, no-leak installation.
