Product Details

The Hedman Hedders 88390 is a full-length long tube exhaust header system designed to deliver significant horsepower gains and improved fuel economy over restrictive factory exhaust manifolds. These headers feature 1-5/8 inch primary tube diameter with 3 inch collectors, providing excellent exhaust flow for street and performance applications.

Key Features:

  • Uncoated mild steel construction with temporary paint finish
  • Long tube design for maximum performance gains
  • Ball and socket style gasketless collector design with 2-1/2 inch reducer outlet
  • Heavy-duty 1/4 inch flange thickness with 5/16 inch collector ring flange
  • Compatible with air conditioning, power steering, and both automatic and manual transmissions
  • Backed by lifetime warranty against defects including cracks in tubes and welds

Each set includes headers, new bolts, head gaskets, ball and socket reducers, mounting hardware, and installation instructions. Sold as a pair. Important: Not legal for street use on 1975 and later model year vehicles—intended for off-road and racing applications only.
