Confirm the vehicle’s exhaust routing, overall length, and body dimensions against the existing muffler, especially on 1979-1990 Buick LeSabre, Chevrolet Caprice, and Cadillac Fleetwood applications. For best results, match the OE-style pipe diameter and inspect adjoining pipes, hangers, and clamps for wear before final assembly.
