Hedman Hedders Debuts Headers for 1978-87 G-Bodies

Ah, the G-bodies–those ’80s-tastic GM cars that everyone secretly wanted to own while the war raged on between Camaros, Firebirds, and Mustangs, this was the platform that gave us the legendary Grand National and GNX coupes that could put any competitor to shame. However, like all things, these vehicles age, and the exhaust system is not immune. That’s why Hedman Hedders has introduced these new headers for 1978-87 G-bodies, which come complete with 1 ½-inch primaries and a 3-inch ball-style collector, and are available in either Hedman’s Standard Duty or Ultra-Duty ELITE construction.

Official Release:

GM’s G-Body platform was the foundation for many of the most memorable and legendary automobiles that hit the streets during the 1980s. The Monte Carlo, Regal, Cutlass and El Camino each had their own unique style and packed some of GM’s most potent V8 engines of the era. Thanks to the platform’s light weight and venerable small block power, G-bodies have become a favorite of gearheads across the country. Now, Hedman Hedders offers a line of smog legal headers for ’78–’87 GM G-Body cars that help enthusiasts coax every ounce of power from their engine while not running afoul of “Johnny Law.”

Hedman’s full-length headers are engineered to deliver maximum exhaust flow while maintaining the factory catalytic converter locations and A.I.R. injection, making them 50-State emissions legal under C.A.R.B. EO#D-167-33 for vehicles equipped with 305cid, 307cid and 350cid V8 engines. Even with their state inspection-friendly status, these headers deliver performance that is far from stock, helping unlock the true potential of your G-body’s small block engine. Hedman builds these headers with 1 ½-inch primaries and a 3-inch ball-style collector, and are available in either Hedman’s Standard Duty or Ultra-Duty ELITE construction. Standard Duty headers are built using 18-gauge mild steel primaries, while the Ultra-Duty ELITE headers feature bullet-proof 3/8-inch flanges and thick-wall 14-gauge primaries. Each set comes complete with header gaskets, bolts and header reducers that easily weld to the car’s exhaust system for a durable, gasket-free connection between the headers and the rest of the exhaust system.

Standard Duty headers for ’78-87 GM G-Body vehicles are available either in an uncoated finish (#68311) or with Hedman’s HTC polished ceramic-metallic coating for protection up to 1,400-degrees Fahrenheit (#66311). The Ultra-Duty ELITE Series headers are coated with a matte finish version of Hedman’s HTC hi-temp coating (#61318). Mounting hardware, instructions, and the mandatory E.O. sticker for your engine compartment are also included. For those looking for more power from their emissions-exempt vehicles, Hedman also offers these headers without A.I.R. injection (#68310, #68316 and #68318). If ground clearance is an issue, Hedman offers mid-length and “shorty” style headers for applications where maximum ground clearance is required.

Features:

  • Legal in all 50 states for vehicles with 305cid, 307cid and 350cid V8 engines
  • Available in either Hedman’s Standard Duty or Ultra-Duty ELITE construction
  • 1 ½-inch primaries and a 3-inch ball-style collector
