The 1970 -72 Chevelle Model year dual exhaust systems consisted of 2 1/2″ head pipes and 2″ tail pipes. All of the big block cars from 1970 -1972 had a dome-shaped resonator which ended at 2 1/2″ allowing for the chrome tip. Our preproduction exhaust kit comes 14 ga aluminized with correct 2 1/2″ head pipes with wrinkles and flats, correct extensions, donuts, flanges, mufflers, 2″ tail pipes with correct resonators welded on, correct GM style clamps, installation instructions, diagrams and sealant. Our exclusive reproduction¬†hangers are available with this system, as well as correct GM heat riser and stainless steel stud kit with correct lock nuts. Ask about our concourse show package¬†for those who like it just a little bit better than original, or our stamped mufflers to really impress the judges.
