Hedman Hedders has been manufacturing quality headers in the USA since 1954. 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 Toyota exhaust system to bolt up, even if it is not perfectly aligned with the header collectors.
The super smooth, 1-1/2 in. primary tube design provides ample exhaust flow to help the carbureted 20R or 22R engine in your Toyota pickup truck or Celica produce maximum horsepower. The compact MID-LENGTH design provides excellent low-end torque for better streetability.
These headers are uncoated, and ship from the factory with a temporary black paint that will burn off when submitted to normal operating temperatures. Should you prefer to have a coated model, this model is also available with a ceramic-metallic finish.
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 against manufacturer defects.
