Now available - Yestertech Headers


    • Fits 54-56 Ford & Mercury, 57 and others soon
    • Dual Exhaust Equalizer required
    • Automatics may retain column shift with some modifications
    • Mandrel Bent 16 gauge, 1.625 OD primaries
    • Choice of 2.25 or 2.5 collectors
    • Laser Cut .25 Thick Flanges, any thicker adds weight penalty
      • Flange surface that contacts head has flat ridge, eliminating need for a gasket
      • The 1.625 primaries are not equal length, but a header with a minimum number of bends also has advantages
      • Primaries are paired in a Tri-Y configuration for best scavenging torque and minimum loss of that great Y-Block Sound!

These headers are much superior to other Y-Block headers on the market
