These are the 1 7/8" primary headers that are original equipment on the
Hurst built cars.
They are a race header without collector flanges to bolt a exhaust system.
Some tubes are slip fit removable and have long collectors. The collectors
aim straight back rather than point towards the driveshaft like the TTI's
They also hang lower below frame rails rather than tucked up close to the floor
as the TTI's. The SS cars set high in the front which gave them the room for these
pipes and a deep sump racer added pan.
