Hedman Shorty Hedders for 1982-97 Camaros and Firebirds make great power, Are Made in the USA and now feature CARB E.O. numbers

Whittier, Calif. – Third and early fourth generation GM F-Bodies are one of the best performance bargains on the market today, thanks to a well-sorted suspension setup, a plethora of aftermarket parts options, and venerable small block powerplants (of the TPI and LT1 variety) that respond well to basic bolt-on performance parts. Now Hedman, the industry leader in tubular exhaust manifold technology, has an assortment of hedders for these cars with a CARB E.O. number (D167-33), making them 50 state legal. This is bolt-on horsepower, Johnny law can’t hassle you about.

One of the easiest ways to squeeze extra power out of your 1982-97 Camaro, Firebird or Trans-Am is with a set of high-flow hedders, but not all tubular exhaust manifolds are created equal. Hedman Hedders begin with 1 5/8-inch primaries and mild steel construction. Part numbers 66471 and 66481 provide Gen3 F-Body owners a couple of options depending on engine and chassis, and both are finished in a high-temperature ceramic coating that looks great and offers protection up to 1,400 degrees. Uncoated versions are also available.

Third-Gen drivers not only see an increase in the engine’s performance, Hedman’s shorty design provides maximum ground clearance–ideal for lowered Camaros and Firebirds–along with the option to run heads with angled spark plugs. All of the F-body models covered by this E.O. number retain the factory catalytic converter(s), and are backed by Hedman’s limited lifetime warranty against manufacturer defects. Hedman even puts five years’ worth of warranty on the HTC finish.

For Fourth-Gen owners, part number 66541 covers 1993-1994 F-Bodies, while 66581 is made for the 1995-1997 models with factory dual catalytic converters. These Hedmans are equipped with many of the same features of the Third Gen shorties like smooth flowing mandrel bend primaries, and no matter which set of hedders they choose, buyers can be sure if they come in a Hedman box, they were made in the U.S.A., like they have been since 1954.
