Walker 55162 Exhaust Pipe for GM Rear Applications

Walker 55162 is a specific-fit exhaust pipe made from aluminized steel for durability and corrosion resistance. It is built with precision benders and fixture-checked for accurate alignment, helping support a straightforward installation on select Buick, Oldsmobile, Pontiac, and Cadillac rear exhaust applications.

Key Features

  • Aluminized steel construction for long-term exhaust service
  • Specific-fit design for select rear exhaust applications
  • 2.25-inch inlet inside diameter and 2.25-inch outlet outside diameter
  • 56.25-inch overall length
  • Pipe connection inlet and outlet for direct exhaust routing
  • Walker 55162 is engineered for precise fitment on supported vehicles

Detailed Product Overview

This Walker exhaust pipe is designed for rear exhaust replacement on select 1986-1991 Buick LeSabre, 1986-1991 Oldsmobile Delta 88, 1986-1990 Oldsmobile 98, 1987-1991 Pontiac Bonneville, and 1986-1987 Cadillac Commercial Chassis, DeVille, and Fleetwood applications. The aluminized finish helps protect the steel pipe from everyday exhaust exposure, while the formed dimensions support proper routing in the factory exhaust path. This part cross-references Four Seasons (e.g., 55161, 83012) for the same application. Walker 55162 is a practical replacement choice when servicing a worn, rusted, or damaged rear exhaust section on these GM full-size platforms.

What This Exhaust Pipe Helps Address

  • Rust-through or corrosion in the rear exhaust pipe
  • Cracks or leaks in the factory exhaust routing
  • Restricted exhaust flow caused by a damaged pipe section
  • Fitment issues from an incorrect replacement pipe
  • Noise from a leaking rear exhaust connection
