1 5/8" Long Tube Headers

The Summit Racing SUM-G9001-9 headers are designed as a long tube, one-piece solution for enhanced exhaust flow. Constructed from durable steel with a silver ceramic coating, these headers offer a 1 5/8 inch primary tube outside diameter and a 2.500 inch collector reducer exit diameter, with a flange thickness of 0.31 inches. Discussions indicate potential fitment issues with certain model years, specifically a noted tightness on the driver's side flange and instances where the collector flange hit the floorboard, preventing bolt installation. While some users with 1969 Camaros reported good fitment and no issues with sending units, users with 1967 models experienced more significant challenges. There is also mention that the headers may lack areas for sending units, potentially requiring modification or omission of sending units.
