For model years 1952-54, Waldron's needs to know if customer is utilizing single exhaust manifolds or dual exhaust manifolds (this affects the driverside manifold).

For systems requiring pipes 2" and up, we use 14 gauge aluminized steel tubing. For pipes less than 2" we use 16 gauge aluminized steel tubing. Mufflers are also constructed of aluminized steel, for longer life.
