Product Details

Common Issues This Muffler Can Address

Installation Notes and Tips
Verify inlet and outlet sizing before installation: 2.25-inch inlet, 2-inch outlet, with offset inlet and center outlet configuration. Confirm the exhaust routing on your 1997-1999 Buick Park Avenue matches the listed dimensions and connection style before final assembly. Because this is a specific-fit muffler, it is intended to align with the original application rather than a universal setup.
Quality Assurance
Walker uses 100% aluminized steel in this SoundFX Direct Fit muffler to improve durability compared with low-carbon steel. Mechanical interior joints and spun-locked heads are used to support long-term structural integrity in normal exhaust service.
