Product Details

The Walker Exhaust 50473 is a premium aluminized steel exhaust Y-pipe designed to deliver a precise OEM-style fit. Featuring a 2.25" outer diameter inlet and 2" outer diameter outlet, this Y-pipe is engineered to merge dual exhaust streams into a single outlet with clean, leak-free connections.

Walker manufactures this pipe using precision mandrel bending equipment and fixture-checks every unit to ensure consistent geometry and correct fitment right out of the box — minimizing installation time and eliminating the need for modifications.

Key Features:

  • Aluminized steel construction for enhanced corrosion resistance and long service life
  • 2.25" OD inlet / 2" OD outlet for accurate sizing and proper exhaust flow
  • Precision-bent and fixture-checked for an exact OEM-style fit
  • Direct-fit replacement — no cutting, welding, or modifications required
  • Designed for quick, straightforward installation

Walker Exhaust is a trusted name in OE-quality exhaust components, and the 50473 Y-pipe upholds that reputation with consistent manufacturing standards and reliable performance. Ideal for restoring proper exhaust flow and maintaining system integrity.
