Product Details

Hedman Hedders 78070 mid-length headers are engineered specifically for 1967-1974 Mopar B-Body and E-Body vehicles powered by Chrysler 361-440 cubic inch B/RB wedge-style engines. These American-made headers deliver improved exhaust flow for increased low-end horsepower and torque over restrictive factory manifolds.

Key Features:

  • 1-3/4 inch diameter CNC mandrel-bent primary tubes for smooth exhaust flow
  • 2-1/2 inch collector diameter with 3-bolt flange attachment
  • 18-gauge mild steel construction with hand-welded joints
  • Unique gasketless ball-and-socket collector design for easier installation alignment
  • 1/4 inch thick flanges for durability and proper sealing
  • Mid-length tube design balances performance and fitment
  • Fits both manual and automatic transmissions (mini-starter required)

What's Included:

  • Pair of headers (left and right)
  • Header flange gaskets
  • Collector bolts and header bolts
  • Reducer adapters

Important Finish Information: These headers ship with a temporary black protective paint that is designed to burn off during normal operation. This coating protects the bare steel during storage and shipping only. For long-term corrosion protection and lower underhood temperatures, apply high-temperature header paint or ceramic coating before installation.

Backed by Hedman's Limited Lifetime Warranty against defects in materials and workmanship. Not legal for street use on 1975 and later model year vehicles—intended for off-road and racing applications only.
