The MagnaFlow Street Series crossmember-back exhaust for 1961–1964 Chevrolet Impala models replaces the exhaust from the crossmember back to produce a deep, resonant signature note and dyno-proven flow. Constructed of corrosion-resistant stainless steel with mandrel-bent 2.5" main piping, two straight-through mufflers and a dual split rear exit, the system is direct-fit via 3D scanning and CNC production and is backed by a limited lifetime construction warranty.
