Detailed Description

Walker 43155 is an exhaust pipe replacement for drivers servicing factory-style exhaust routing on compatible compact truck applications. This part is built from steel with an aluminized finish and formed to the specified dimensions for a direct replacement path in the exhaust system. It is a fitment-specific solution for 1985-1993 Chevrolet S10, 1991-1993 GMC Sonoma, and 1985-1990 GMC S15 models. This part cross-references Dorman - HELP 38439 for the same application.

Common Repair Uses

  • Replacing a rusted or damaged exhaust pipe section

  • Correcting exhaust leaks at the flange or pipe connection
  • Returning factory-style routing on Chevrolet S10, GMC Sonoma, and GMC S15 trucks
  • Addressing fitment issues caused by bent or mismatched aftermarket piping

Installation Notes and Tips

Verify inlet and outlet dimensions before installation: 2.25 inches on both ends. Confirm the 2-bolt welded flange with spherical flare matches the existing connection point on the vehicle. Because this is a specific-fit exhaust pipe, compare the original routing and length to the 27.5-inch replacement before final assembly. Walker 43155 is commonly selected for direct replacement work on Chevrolet S10 and GMC Sonoma exhaust systems.
