- Waldron's has brought this muffler back to provide a close match to the original sound, enhanced flow rate from the original, while maintaining the OE look and size. The interior design is derived from the OE Pontiac part. Muffler cavities are packed with sound absorbing materials to compensate for the increased sound levels created by the larger interior diameters. The muffler dimensions are; 4.75 inches X 9.75 inches oval cross-section. The case is 22.75 inches in length with an over-all of 27.75 inches.
