Hedman Hedders HTC Coated Headers; 1-5/8" Tube Diameter; 3" Collector; Full Length Design
Hedman's Standard-duty, Uncoated Hedders are manufactured using 18 gauge, mandrel bent primary tubes (some models built using thicker 16 or 14 gauge tubing), and 1/4 flanges (some models use 3/8" flanges).
Hedman Hedders has been manufacturing quality headers in the USA since 1954, and classic musclecars is their specialty. Each set uses mild steel, smooth flowing, CNC mandrel bent tubes, that are hand-welded to ensure each pair is identical to the next. Hedman's unique, gasketless ball and socket collector design allows your SB Chrysler's exhaust system to bolt up, even if it is not perfectly aligned with the header collectors
These HTC coated, LONG-TUBE headers fit a variety of 1967-1974 MOPAR passenger cars powered by Chrysler's 273-360 LA engine (inline port pattern only). Included in this list of popular models are 1970-74 Dodge Challenger, '67-74 Plymouth Barracuda, '66-74 Dodge Charger, '68-74 Plymouth Roadrunner 67-76 Dart, Duster, Super Bee and Valiant (check the application listings for exact fitment). These headers fit both manual and automatic transmission models, however, modification to the shift linkage may be required. The smooth 1-5/8 in. tube design provides ample exhaust flow to let your Chrysler 273-360 (LA) engine produce additional horsepower and torque
Each set includes a pair of gaskets, header flange bolts and collector bolts. No collector gasket is needed
Hedman Hedders is so confident in the quality of its headers that these headers are factory backed by a Limited Lifetime Warranty. These headers have a high temperature, POLISHED-SILVER ceramic finish that resists corrosion, and can withstand temperatures up to 1400 degree F. This finish is covered by a 5-year factory warranty, in addition to Hedman's standard lifetime header warranty

Hedman Hedders, began as a one man shop in 1954. Bob Hedman, founder of Hedman Hedders, sold his highly sought after exhaust tubes to fellow racers on the salt flats of the Mojave Desert. But, what started out as a way to make a few bucks to pay for Bob’s racing hobby, quickly turned into the premier hedder manufacturer for both the racing and street hedder marketplaces.
