65-71 Jeep Headers 231 V6

The 65-71 Jeep Headers 231 V6 from Hedman is a street-tuned exhaust manifold upgrade designed for classic Jeep CJ models equipped with the GM 231 V6 engine. These headers exist to unlock exhaust flow potential that stock cast iron manifolds simply cannot deliver, making them essential for any enthusiast looking to improve throttle response, fuel efficiency, and overall engine breathing on vintage off-road and street-driven Jeeps.

Constructed from mandrel-bent steel tube with 1.5-inch primary runners, these headers consolidate exhaust gases into a 2.5-inch collector outlet, reducing backpressure and scavenging effects across the RPM band. The black paint finish provides corrosion resistance and a clean, finished appearance under the hood, while the included gaskets and hardware eliminate guesswork during installation. This design prioritizes street drivability and compatibility with stock intake manifold clearances typical of 1965–1971 CJ platforms, making bolt-on installation straightforward for most mechanically competent builders.

These headers serve restomod builders, weekend off-roaders, and classic vehicle enthusiasts who need improved exhaust scavenging without sacrificing factory mounting points or requiring frame modifications. The pair configuration ensures symmetric flow for both cylinder banks, optimizing mid-range torque where vintage Jeeps spend most of their operating time. Compatibility is confirmed for 1965–1971 Jeep CJ models with GM 231 V6 powerplants; verify your engine bay dimensions (16.4 x 8.5 x 39.6 inches) before purchase to ensure proper fitment with your current intake configuration and surrounding components.
