Detailed Product Description

The Walker Quiet-Flow SS 21282 exhaust muffler is a specific fit part designed for Chevrolet and GMC trucks such as the C1500, C2500, and K1500. Its oval-shaped body measures 9 inches in width, 7 inches in height, and 24 inches in length, with an overall length of 29 inches. The muffler features two 2-inch inside diameter inlets arranged in an offset configuration with a 2.625-inch offset, and a single 2.75-inch outside diameter outlet, also offset. Constructed from stainless steel with an aluminized finish, this muffler offers resistance to corrosion and heat, ensuring durability under typical exhaust system conditions.

Installation Notes and Tips

This muffler is designed for specific fitment and requires proper alignment of offset inlet and outlet pipe connections. Ensure inlet and outlet pipe diameters match the vehicle’s exhaust system (2-inch inlets and 2.75-inch outlet). Professional installation is recommended to maintain exhaust integrity and avoid leaks. The muffler is not reversible or tunable, so correct orientation during installation is essential.
