Please check notes in each part listing to ensure the Muffler is correct for your 1980 CADILLAC FLEETWOOD with a 6.0L 368 engine. AP EXHAUST & WALKER are competing brands, and each brand's Muffler may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Muffler fits only certain 1980 CADILLAC FLEETWOOD models.

Clicking a "More Info" link will display a picture and/or other details about that Muffler in a separate window (you may need to turn off your pop-up-blocking software for this to work).

After choosing a Muffler, click the "Add Part" button. Shipping costs will be shown on the Shopping Cart page. You may use your browser's Back button or click "Find More Parts" to find more Exhaust parts, other CADILLAC FLEETWOOD parts or parts for a different vehicle. Please try our Interactive Catalog (click link above) for faster searching. Both catalogs use the same shopping cart so any auto parts you've already chosen for your 1980 CADILLAC will not be lost if you switch.
