Detailed Description

This exhaust pipe is engineered for vehicles that used a welded OE exhaust assembly, making it a practical replacement when the center section needs service. The aluminized steel material provides a common OE-style balance of durability and corrosion resistance for everyday exhaust repair.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Repair Uses

• Replacing a rusted or perforated center exhaust pipe
• Restoring exhaust flow after OE pipe damage
• Repairing a leaking welded exhaust assembly
• Addressing exhaust noise from a failed center section
• Returning Buick Park Avenue, Buick LeSabre, or Pontiac Bonneville exhaust routing to OE-style configuration

Installation Notes and Tips

Verify vehicle year, make, model, and center-position fitment before installation. Because the OE system was a welded assembly on the listed applications, related exhaust parts noted in the vehicle service information should be inspected and replaced as needed during repair. Confirm alignment and sealing surfaces before final tightening.
