EX41160 ‘59-’64 Cadillac Headers with 472 / 500 / 425 Swap, 1 3/4″

Mid length headers for ‘59-’64 Cadillac (and X-frame ’65 Cadillac) with 472 / 500 / 425 swap.

Premium mid length header. Fits ’59-’64 (and X-frame ’65) with 472 / 500 / 425 RWD swaps with little or no mods, may also fit some ’54-’58 swaps. CNC Mandrel bent, 3/8 flanges, 3″ collector. 1 3/4″ primaries.

Note that these use a clamp-on collector (included), rather than the traditional 3-bolt collector, due to space limitations.

Easy fit, no hammer required – properly designed to fit the applications as designed, and perform great.

These headers are manufactured using fully CNC mandrel bent thick wall aluminized tubing, TiG welded in a fixture, with 3/8 flanges, that are machined flat after welding for a reliable seal.

They are a mid-length design, designed for optimum performance from stock to performance builds. They do not hang down low where they will be in danger of causing a ground clearance problem. Higher end builds (over 500 real HP) may benefit from larger tube headers, but the 1 3/4″ headers perform well in most street combinations well into the mid-600-HP range.

Note: Headers are designed to fit listed applications with no further modification, assuming the engine is mounted in the location we mount them. Different installations may require custom fitting.

Note: Standard header flanges, factory heads, and Bulldog / MTS heads all use the ‘standard’ exhaust bolt pattern (2 bolts per exhaust port). If you have any of these heads, you want headers with the ‘standard’ header flange. BoogieMan flange headers only fit BoogieMan heads. They have 3 bolt holes per exhaust port. Early BoogieMan heads only have the BoogieMan pattern (3 bolt holes per port), later BoogieMan heads have both patterns (5 bolt holes per port), and can use either style of header flange.
