This mandrel-bent crossmember-back exhaust system is custom designed for most 1964-1972 GM A-body cars and is perfect for the person looking for true dual exhaust system. System features include all mandrel-bent 2.50-inch aluminized steel tubing, an H-pipe to equalize the exhaust gas pressures and sound for maximum performance and maximum clearance and includes two styles of tailpipe exits. Designed for an easy fit, these systems include all necessary parts, hardware, and instructions for an easy installation. Covered by Flowmaster's 3-year Limited Warranty. Includes Flowmaster's 50 Series Delta Flow Chambered Muffler. The three chamber design utilizes Flowmaster's Delta Flow® technology along with an internal tuning chamber to reduce sound inside the vehicle. Provides the same performance and exterior tone characteristics as the two chamber, but with less interior resonance. Constructed of 16 gauge aluminized steel and fully MIG welded for maximum durability.
