Hello all soI bought my 71 mach 1 with a 351 4v in it. It has hooker headers and dynamax super turbo but they were rusted and had holes. I don't want to sound like an idiot but in all honesty it sounded good and when you got into it it sounded great. The car came with a new set of dynamax super turbos so I installed them today. The car really sounds like a dog and doesn't seem to run as well and has lost all of the crackling it had when you let off the gas quick? Any thoughts?
