HEDMAN HEDDERS TIGHT TUBE HEADERS; MOPAR 318-360; 1-5/8 IN. TUBES; UNCOATED

<p>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. These headers use Hedman's patented TIGHT TUBES chamshell-style collector that allows for a low-profile header design, while still providing beneficial exhaust flow improvement over factory manifolds.</p><p>These uncoated, TIGHT-TUBES headers fit a variety of 1967-1974 MOPAR passenger cars powered by Chrysler'S 273-360 LA engine (inline port 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). The flat-style collector also makes these headers ideal for SB Chrysler equipped street rods and custom projects. These headers fit both manual and automatic transmission models, however, a mini-starter must be used, and modification to the shift linkage may be required. The smooth 1-5/8 in. tubes flow into the large, yet flat, collector, and provide improved exhaust flow, over factory manifolds, to let your Chrysler 273-360 (LA) engine produce additional horsepower and torque.</p><p>These headers are uncoated, and ship from the factory with a temporary black paint that will burn off when submitted to normal operating temperatures. For protection against the element and lower underhood temperatures, these headers are also available with a silver or black ceramic-metallic finish.</p><p>Each set includes a pair of header and collector gaskets, header flange bolts and collector bolts.</p><p>Hedman Hedders is so confident in the quality of its headers that these headers are factory backed by a Limited Lifetime Warranty.</p>
