Product Details

The Hedman Hedders 21143 is a ball and socket style header reducer designed to connect a 3-inch header collector to a 2-1/2 inch exhaust system while retaining oxygen sensor capability. This reducer features a gasketless ball and socket design that provides up to 20 degrees of connection flexibility, making installation easier when pipes don't align perfectly.

Key Features:

  • 3-inch collector inlet to 2-1/2 inch outlet diameter
  • Ball and socket style connection eliminates gaskets
  • Integrated 18mm O2 sensor bung for proper sensor placement
  • 3-bolt triangular flange design for secure mounting
  • Manufactured from mild steel construction
  • Includes all necessary bolts, nuts, and washers
  • 0.3125-inch flange thickness for durability
  • Made in the USA

This reducer is designed to be welded to your exhaust system, then bolted to Hedman's ball and socket style header collectors. The gasketless design provides a reliable seal while the flexible connection simplifies installation. Each package contains one reducer with complete hardware. Note: Not legal for street use on 1975 and later model year vehicles; intended for off-road use only.
