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.

Common Repair Uses

  • Replacing a rusted or damaged exhaust pipe section
  • Restoring proper exhaust flow after pipe corrosion or cracking
  • 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.
