This mandrel-bent headers-back exhaust system is custom designed for most 1964-1967 GM A-body cars and is perfect for the person looking to build a true dual exhaust system. This system comes complete minus the mufflers and hangers. This allows you to choose the sound level of the Flowmaster performance mufflers you desire for your vehicle. System features include all mandrel-bent 3.00-inch aluminized steel tubing, an H-pipe to equalize the exhaust gas pressures and sound for maximum performance and maximum clearance. Designed for an easy fit, these systems covered by our 3-year Limited Warranty. Notes: Requires 3.00-inch Offset Inlet/Opposite side Offset Outlet such as part# 943048 (Super 44 Series) or 53058 (Super 50 Series) mufflers.

Manufacturer installation notes
