Product Details
This Walker Quiet-Flow SS assembly is engineered as a rear exhaust muffler replacement for 2013-2014 Ford Edge and 2013-2015 Lincoln MKX models.

Installation Notes and Tips
Fits 2013-2015 Lincoln MKX, rear. Fits 2013-2014 Ford Edge, rear. Verify inlet diameter, outlet configuration, and overall length against the original exhaust before installation. Because this is a direct-fit muffler assembly, matching the rear exhaust routing and hanger locations is important for proper alignment.
