This header-back exhaust system is custom designed for 1964-72 GM A-body cars and is for the person looking for a complete 2.50-inch dual exhaust system with a moderately aggressive exterior tone and a moderate interior sound. With easy fit in mind, these aluminized steel systems feature all mandrel-bent tubing, an H-pipe to equalize the exhaust pressures for maximum performance and deep sound. The system includes a pair of specially selected Super 40 mufflers, mandrel-bent tailpipes tucked up out of the way for maximum clearance and your choice of two tailpipe exit styles. Like all Flowmaster systems, benefits include improved throttle response, power, and mileage. Designed for an easy fit, these systems include all necessary parts and hardware for an easy installation. Notes: Does not align with the factory bumper cutouts on an Oldsmobile 442.
