Detailed Description

The Walker Quiet-Flow SS line focuses on stainless-steel durability, precision fit, and controlled exhaust tone. Part number 21248 uses a premium, specific-fit design with an irregular round body shape, offset inlet and outlet placement, and an angle-trimmed tailpipe outlet to match the intended exhaust routing. This muffler is a practical replacement choice for Jeep Grand Cherokee applications where fit accuracy, flow characteristics, and a factory-style sound matter.

What It Helps Solve

• Alignment issues during rear exhaust replacement on the vehicle

Installation Notes and Tips

Fits 2011-2021 Jeep Grand Cherokee, rear left. Verify inlet and outlet orientation, flange style, and hanger placement before installation. The offset inlet and outlet layout should be matched to the existing exhaust routing, and the angle-trimmed tailpipe outlet should be positioned to follow the original system geometry.
