Walker 42276 Exhaust Pipe for GM Trucks

Walker 42276 is a specific-fit exhaust pipe built from aluminized steel for durability and consistent fitment. It is made with precision bending and fixture checking to help ensure accurate alignment during installation on select Chevrolet and GMC full-size trucks.

Key Features

  • Aluminized steel construction for corrosion resistance and long-term exhaust service
  • 3-inch inlet and 3-inch outlet pipe connection
  • 14-inch overall length with a 5-inch bend radius
  • Compression bend type for formed exhaust routing
  • Specific-fit design for direct application matching
  • Walker 42276 exhaust pipe for select Chevrolet C1500, Chevrolet K1500, GMC C1500, and GMC K1500 models

Detailed Description

This Walker exhaust pipe is engineered for exhaust system repair on 1988-1993 Chevrolet C1500, Chevrolet K1500, GMC C1500, and GMC K1500 applications with a 3-inch muffler inlet. Select listings also require the correct welded-converter configuration, so fitment should be matched to the vehicle’s exhaust layout before installation. Walker 42276 is a direct-fit exhaust pipe solution for owners replacing a damaged or rusted section on these GM trucks.

This part cross-references AP Exhaust 28591 for the same application.

What It Helps Address

  • Rust-through or corrosion in the exhaust pipe section
  • Exhaust leaks caused by cracked or damaged tubing
  • Fitment issues when replacing a worn pipe on a 3-inch muffler inlet system
  • Restricted exhaust flow from a deteriorated pipe section
  • Repair needs on 1988-1993 Chevrolet C1500 and GMC K1500 exhaust systems

Installation Notes and Tips

Confirm the vehicle has a 3-inch muffler inlet and verify whether the exhaust system uses a welded converter before ordering. This pipe is a specific-fit part, so matching the original routing and connection style is important for proper installation. For welded assemblies, replace all required parts as noted in the fitment data to complete the repair correctly.

Quality Assurance

Walker manufactures this pipe from aluminized steel and uses precision benders with fixture checking to support accurate fitment and consistent build quality. The Walker 42276 part number is associated with a direct replacement exhaust pipe for select Chevrolet and GMC truck applications.
