The MagnaFlow 16724 is a crossmember-back (cat-back) performance exhaust for the 1959-1964 Chevrolet Bel Air, Biscayne, and Impala, sold under MagnaFlow's C/B 59-64 name. It replaces the factory tailpipe-and-muffler run behind the rear crossmember, so the sound and exhaust flow change while the factory catalytic converter stays in place. For a buyer restoring or driving a '60s full-size Chevy, that means a deeper exhaust note and less restriction than a worn stock system, without rebuilding the front of the car. Search terms that match this part include 1961 Impala cat-back exhaust, 1962 Impala crossmember-back exhaust, 283 small block Impala exhaust, and 409 Bel Air exhaust upgrade. Fitment varies by year, trim, and engine, so confirm the exact application against your car before ordering. Owners on user forums typically cut and weld the system to fit, so plan for some fabrication time on the install.
