DynoMax's computer-controlled, precision machining means flatter, truer flanges for a better seal.  Any distortion in the plane of a flange surface can cause exhaust gas leakage.
 
Any construction at bends results in restriction of flow.  DynoMax primary tubes have mandrel bends for up to 35% better flow than ordinary, serrated bent tubes.

    
Jet-Hot luster ceramic coated headers are covered 100% inside and out with a protective surface that won't discolor, chip, or rust.  Offering easier gas flow and an increase in horsepower, Jet-Hot coating lasts 14 times longer than chrome, 140 times longer than paint, and meets the DynoMax 5000-hour salt spray test with no failures.
