MagnaFlow Street Series crossmember-back for 1960–1972 Chevrolet CST-10/CST-20 trucks supports a range of engines and produces a deep, resonant signature note at aggressive exterior and moderate interior levels. The crossmember-back layout uses mandrel-bent 2.5in piping and two straight-through mufflers with a dual split rear behind-the-rear-tires exit. It’s 3D-scanned for direct fit and CNC-produced from corrosion-resistant stainless steel.
