BRAND NEW FLOWTECH LONG TUBE HEADERS, PAINTED FLAT BLACK, COMPATIBLE WITH CHEVY & GMC PICKUP TRUCKS, PRODUCED BY HOLLEY PERFORMANCE PRODUCTS

FLOWTECH HEADERS ARE THE PERFECT COMBINATION OF PERFORMANCE AND VALUE. FLOWTECH LONG TUBE HEADERS ARE PRECISION ENGINEERED USING MANDREL BENT TUBING, FORMED COLLECTORS AND 5/16" FLANGES WITH SEALING RINGS FOR A LEAK-FREE SEAL. ALL MOUNTING HARDWARE AND GASKETS ARE INCLUDED FOR A SIMPLE INSTALLATION. THIS HEADER IS COATED IN A HIGH HEAT RESISTANT BLACK PAINT FOR A STEALTHY APPEARANCE.

NOTE: CERAMIC COATED HEADERS REQUIRE SEVERAL HEAT CYCLES TO FULLY CURE BEFORE THEY WILL WITHSTAND EXTREME HEAT. FLOWTECH RECOMMENDS USING CAST IRON EXHAUST MANIFOLDS OR OLD HEADERS TO BREAK IN NEW ENGINES TO AVOID COATING DAMAGE.

NOTE: THE USE OF HEADER WRAPS CAN CAUSE THE HEADER TUBES TO CRACK OR RUST DUE TO EXCESSIVE HEAT AND MOISTURE BUILD-UP. FLOWTECH DOES NOT RECOMMEND THE USE OF HEADER WRAPS.
