The Hedman Hedders 79170 are standard-duty, full-length exhaust headers designed for 1972-1991 Dodge Ramcharger, Plymouth Trail Duster, and W-Series 4WD pickups equipped with small block Mopar 318 or 360 cubic inch engines. These long tube headers deliver improved horsepower and torque gains over restrictive factory manifolds, making them an excellent performance upgrade for classic Dodge and Plymouth trucks.

Finish: These headers ship with a temporary protective paint coating designed to prevent rust during manufacturing and shipping. This coating is not designed to withstand high heat and will burn off during use. It is recommended to apply high-temperature header paint or ceramic coating for long-term protection and appearance.

Backed by Hedman's limited lifetime warranty on construction, these headers represent exceptional value for Mopar enthusiasts looking to unlock additional performance from their classic 4x4 trucks.
