1 The Flowmonster series of absorption style mufflers deliver a moderate tone for the enthusiast looking for a deeper, more aggressive exhaust note than most OE (Original Equipment) mufflers, unlike the racey exhaust note associated with "chambered" style mufflers. 3 Interior construction features 3.50 inch "straight-through" perforated 409 stainless steel tube surrounded by high-temperature sound absorption packing material which helps to deliver a deeper, mellower exhaust note. The internal design is reversible allowing the flexibility to be installed in either direction to best accommodate fitment with the intended vehicle. The fully MIG-welded 409 Stainless Steel material is embossed with the "FLOWMONSTER" logo on the case.

Features:

  • 409 Stainless Steel construction for superior corrosion resistance and good looks
  • Interior construction features high-temp interior sound absorption material delivering a deeper, mellow exhaust tone
  • Perforated High-Flow straight-through tube design for increased exhaust flow
  • Moderate increase in interior tone over most OE mufflers
  • A stainless steel performance muffler at an economical price
  • Internal Design is reversible allowing flexability to be installed in either direction
  • Sold Individually
