      • Stainless steel construction
      • Dyno tuned for maximum performance
      • Patented laminar flow technology
      • Made in the USA
      • Limited lifetime warranty

      The Flowmaster Super HP-2 Series mufflers incorporate the laminar flow technology from the classic HP-2 muffler and wrapped it in a new compact size. Laminar flow technology offers the same great performance benefits and moderate tone that you would expect now in a new sleek styling.

      The compact design allows for easier installation. The mufflers are constructed out of black powder coated 409s stainless steel or a polishable 304s stainless steel that can be shined to ma mirror finish with a little elbow grease. Multiple inlet and outlet diameters make it a versatile muffler for many applications.

      California Residents: Prop 65 Warning


      Limited Lifetime Warranty

      Lifetime Limited Warranty applies to Flowmaster stainless steel mufflers (excluding FlowFX series), all stainless steel exhaust systems
      (including FlowFX series), stainless steel pipes, air intake kits and oiled type filters (except cleaning kits), and other stainless steel exhaust
      accessories (except exhaust tips and racing products).

      Flowmaster warrants the products mentioned above against defects in materials and workmanship for the period set forth below, when they are
      owned by the original purchaser and remain installed on the vehicle on which they were originally installed. This warranty is void if the product
      was not installed properly on the vehicle, was installed on a vehicle for which it was not designed, or was removed from the vehicle on which it
      was originally installed and reinstalled on another vehicle. This warranty shall not apply to normal wear, including interior/exterior sound levels,
      cosmetic issues such as coatings and material discoloration, any product that was installed on a racing vehicle, installed improperly or contrary to
      Flowmaster instructions, altered, misused, repaired, damaged from an accident, collision, undercarriage road impact or debris, or willful or
      negligent act. Note that all “straight-through” mufflers which use sound absorbing material inside the muffler to cancel sound…will degrade over
      time. This degradation of sound absorbing materials is considered “normal wear”…not a material defect.


      Flowmaster mufflers requires permanent modification if installing onto a factory exhaust system. Cutting and welding is required. Professional installation is recommended.
