What is the benefit of mandrel bent tubing?

Mandrel bending allows the tubing to maintain its internal diameter and shape through bends, unlike crush bends which can constrict flow. This smoother flow path can improve exhaust gas scavenging and lead to better engine performance.

Does this Y-pipe include all necessary hardware for installation?

Yes, the Y-pipe comes with high-quality hardware and thorough instructions to help ensure a professional, no-leak installation.

Can this Y-pipe be used on a vehicle registered in California?

No, this product is not legal for use on catalytic converter-equipped vehicles for street or off-highway use in California or states that have adopted California emissions regulations. It is intended for closed-course competition use only.

Product Details

The 409 Series stainless steel tubing in this JBA Y-pipe is mandrel bent, meaning it maintains its shape through the bends. This helps keep exhaust gas flowing smoothly, which can lead to a noticeable increase in performance and a deeper exhaust note compared to stock piping. It's designed to work well with JBA's stainless steel headers, creating a more complete performance exhaust system for your Tundra.

This Y-pipe is built with heavy-duty flanges for a solid connection and includes factory-style hangers to ensure it mounts up correctly. You'll also get the necessary hardware and instructions for a professional installation that aims for a leak-free seal. The hand-polished finish gives it a custom look under your truck.

Keep in mind that this part is not legal for use on street-driven vehicles in California or states that follow California emissions standards due to its impact on emissions control systems. It's intended for off-road or competition use only.
