Flowmaster header back Fit
This is first exhast that really fit and I have tried a lot of them! most are modified E or B-body kits that are shortened to fit and don't. the proof is in the tail pipes . A-bodys are tight and if not bent right you windup cutting to fit. this kit installs in 2 hours with the cutting and welding for the header connection thank you Flowmaster!
