INCLUDES A PAIR OF 2 1/2" REDUCERS TO COMPLETE THE INSTALLATION. CERAMIC HOT COATING (CHC) IS A HEAT RESISTANT, CERAMIC COATING APPLIED TO THE OUTSIDE OF THE HEADER. THIS COATING WILL REFLECT HEAT, WHICH HELPS RETAIN MORE HEAT WITHIN THE HEADER TUBE, WHILE SIMULTANEOUSLY SPEEDING UP THE EXHAUST FLOW. NOT ONLY WILL THIS COATING HELP YOU MAKE MORE HORSEPOWER, IT ALSO KEEPS YOUR HEADERS RUST-FREE, LOOKING GREAT, AND LASTING LONGER (WHEN PROPERLY MAINTAINED). IF YOU ARE LOOKING FOR A QUALITY FINISH FOR YOUR HEADERS, THIS IS IT. GOOD TO 1300 DEGREES.
