Detailed Description

AP Exhaust 700234 is built as a direct-fit exhaust muffler for vehicles that need a replacement with factory-style dimensions and routing. The 22-inch body length, 26-inch overall length, 4.06-inch body height, and 10.5-inch body width support a fitment profile suited to select GM and Jeep platforms, including 2002-2007 Buick Rendezvous, 2002-2007 Jeep Liberty, 2001-2005 Pontiac Aztek, 1994-1999 Buick LeSabre, 1994-1999 Pontiac Bonneville, and other listed applications.

This part number, 700234, is a practical choice when replacing a worn or damaged muffler on compatible vehicles.

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

What It Helps Address

• Rust-through or corrosion in the original muffler body
• Exhaust noise caused by a failing internal muffler structure
• Factory exhaust tone that has become louder over time
• Replacement needs on vehicles with a welded OE exhaust assembly
• Fitment-specific repair for Buick Rendezvous, Jeep Liberty, and Pontiac Aztek exhaust systems

Installation Notes and Tips

Verify inlet and outlet orientation before installation: this muffler uses a center inlet and right-center outlet with 2.25-inch pipe connections. Some listed Jeep Liberty applications note that the OE system was a welded assembly, and related parts may need to be replaced together for a complete repair. Confirm vehicle year, make, model, and exhaust routing against the fitment list before ordering.
