Standard-Duty Headers For Various Camaro, Chevelle, El Camino, Nova, Regal, Cutlass, Grand Prix & Others; SB Chevy 283-400; 1-5/8 in. Mid-Length Tubes, 3 in. Collector; Non-E.O. ; Uncoated Mild-Steel

Hedman Hedders has been manufacturing quality headers in the USA since 1954, and they've been manufacturing long and MID-LENGTH tube headers for Chevy passenger cars for decades. Each set uses mild steel, smooth flowing, CNC mandrel bent tubes, that are hand-welded to ensure each pair is identical to the next. Hedman's unique, gasketless ball and socket collector design allows your Small Block Chevy exhaust system to bolt up, even if it is not perfectly aligned with the header collectors.

These uncoated, MID-LENGTH tube headers are one of the most versatile headers Hedman Hedders manufacturers. While we've seen them on rare builds, like a SB Chevy equipped Studebaker, these MID-LENGTH headers are actually cataloged to fit Small Block Chevy V8 powered, 1967-81 Chevy Camaros; 1964-1987 GM A-Body and G-Body vehicles (Buick Regal, Chevy Chevelle, El Camino, Monte Carlo, Olds Cutlass, Pontiac Grand Prix); '68-79 Chevy II and Nova. Heck, they even fit 1984-2004 Chevy AstroVans. The smooth 1-5/8 in tube design provides ample exhaust flow to let your 283-400 SB Chevy engine breathe easy, and improve horsepower and torque over stock manifolds.

These headers are uncoated, and ship from the factory with a temporary black paint that will burn off when submitted to normal operating temperatures. For protection against the element and lower underhood temperatures, these headers are also available with a silver or black ceramic-metallic finish.

Each set includes a pair of gaskets, header flange bolts and collector bolts. No collector gasket is needed.

Hedman Hedders is so confident in the quality of its headers that these headers are factory backed by a Limited Lifetime Warranty.

  • Handcrafted, Mild Steel Construction.
  • The Mid-Length Tube Header Design Provides Significantly More Low and Mid-range Power than Cast Manifolds, and Provide Better Ground Clearance And Component Compatibility Than Long Tube Headers.
  • Ball & Socket Collector Design requires No Gasket, and Allows For More Exhaust System Misalignment than Old School, Gasket-Style Header Collectors
  • Includes All The Necessary Mounting Hardware, Gaskets and Reducers (exhaust adapters)
  • Limted Lifetime Warranty On Construction, Five Year Warranty on Factory-Applied Header Coating!
  • Proud To Say, Made In The USA, Since 1954!
