    Sleek, Compact Size

    Flowmaster's Super HP-2 Series Mufflers are designed with laminar flow muffler technology, and feature the same laminar core as the classic HP-2 muffler. This technology produces great performance benefits with a moderate exterior sound and minimal interior resonance to deliver a terrific '50s style street rod tone. Housed in a sleek, compact square case, the overall reduced exterior sizing is ideal for easy fitment. These mufflers are available in either a 409S stainless steel case or a polishable 304S stainless steel case with inlet and outlet sizes ranging from 2, 2.25. and 2.5 inches in diameter. The shorty length muffler measures 4" W x 5" H x 12" L and the standard length muffler measures 4" W x 5" H x 18" L.

    Features:
  • Moderate Exterior Tone
  • Compact Square Case
  • Stainless Steel Construction
  • Dyno Tuned for Maximum Performance
  • Patented Laminar Flow Technology
