Walker 40571 Aluminized Steel Direct-Fit Exhaust Y-Pipe

The Walker 40571 is a direct-fit aluminized steel exhaust Y-pipe designed to merge dual exhaust outlets from the manifold into a single pipe leading to the muffler. Built to OE specifications, this Y-pipe restores proper exhaust flow and system integrity when the factory pipe becomes damaged, corroded, or begins leaking.

Key Features:

• Aluminized Steel Construction: Durable aluminized coating provides excellent resistance to corrosion and heat for long service life
• Precision-Bent Design: Manufactured using precision benders and fixture-checked to ensure accurate OE-style routing and fitment
• 3-Bolt Flange Inlet: Secure connection at the manifold using a standard 3-bolt flange attachment
• Slip-Fit Outlet: 3.00-inch slip-fit outlet for straightforward downstream connection
• Direct-Fit Replacement: Vehicle-specific design installs without cutting or welding in most applications
• No Oxygen Sensor Bung Included: If an O2 sensor is required, drill a 0.5-inch hole at the sensor tap location
• Sold Individually: Includes the Y-pipe only; gaskets, hardware, and catalytic converter not included

The Walker 40571 Y-pipe is compatible with 117.5-inch and 131.5-inch wheelbase applications. Walker exhaust components are engineered to deliver OE-style performance, appearance, and reliability, making this an ideal replacement for worn or leaking factory exhaust pipes.
