    The Best Header Bolts!!

    12 hr shop time to install long tube headers and lose stock bolts took the fun out of it. I had an exhaust leak in the same spot on both sides, not a worry anymore. It was worth every penny not to smell exhaust flooding the inside while driving. Long tubes sound better too!
