The 18895 muffler maintains these standards, offering a straightforward installation process and consistent exhaust performance for Buick Century and Pontiac Grand Prix vehicles.

Detailed Product Description

This Walker exhaust muffler features a robust steel body finished with aluminized coating to resist corrosion and extend service life. The oval shape and specific dimensions—11 inches body width, 5.5 inches body height, and 15 inches body length—are designed to match the original equipment specifications. The muffler includes a single 2-inch inside diameter inlet with an offset pipe connection positioned 3.75 inches from the center, and a single outlet tip with a 2.25-inch outside diameter, also offset. This combination muffler type balances sound attenuation and exhaust flow, suitable for the targeted Buick and Pontiac models.

  • Reduces exhaust noise while maintaining proper flow
  • Addresses exhaust leaks caused by rust or corrosion
  • Restores factory exhaust system fit and function
  • Helps maintain emissions compliance by ensuring proper exhaust routing

Installation Notes and Tips

The Walker SoundFX Direct Fit muffler 18895 is designed for direct replacement, matching the original muffler's inlet and outlet sizes and offset configurations. Ensure the existing exhaust pipe matches the 2-inch inlet diameter and offset position for proper fitment. This muffler is not reversible or tunable, so correct orientation during installation is essential. Professional installation is recommended to verify secure connections and prevent exhaust leaks.

Quality Assurance

Constructed from aluminized steel, this muffler offers corrosion resistance suitable for typical driving conditions. Walker provides consistent manufacturing standards for the SoundFX Direct Fit line, ensuring reliable fit and function.
