    2452HKR Notes:

    • Does not fit with an angle plug or raised port heads. Breaking in an engine with ceramic-coated headers WILL result in damage to the coating and will VOID all warranties. Hooker recommends using cast iron exhaust manifolds or old headers during your engine break-in period to avoid damaging your coated damage
    • The use of header wraps can cause the header tubes to crack or rust due to excessive heat and moisture build-up
    • Hooker does not recommend the use of header wraps as this will void the warranty
    • Hooker long tube headers do not come with header reducers
  • This part is only legal for sale and use on Uncontrolled (Non-Emissions Controlled) Vehicles or on vehicles used solely for the purposes of closed competition racing.

  • All Budget Headers are NOT Created Equally!
    Hooker's Competition Series Headers come in your choice of finishes and are engineered to perform at a reasonable price! To let your engine really breath Hooker utilized 16 gauge (.049'' thick) steel tubing attached to long transition style collectors! Giving you a serious increase in flow over other brand headers without a loss in the backpressure most engines need to perform! After years of testing, Hooker has discovered that a machined 5/16'' header flange offers enough flex to hold the gasket tight to each exhaust port, and enough rigidity to keep everything properly tied together.
