I had Hookers on my car , and they hit everywhere , maybe the roads are like glass in your area , with no speed bumps . Mine were pancaked , and no my shocks are perfect and I did not blast into driveways or ditches . Ive yet to see an A body with cheap *** headers that DON''T have 1 or 2 flattened tubes , unless it's a show car that never drives . Been driving Darts with headers since 1970 , and they hit then , hit now , only headers that don't hit bottom are TTI and Dougs , at least on the shitty roads up here and northern states .
