Description

FlowMonster absorption mufflers deliver a moderate tone for the enthusiast looking for a deeper, more aggressive exhaust note than most OE mufflers, unlike the exhaust note associated with chambered-style mufflers.

The interior construction features a 3.50 in. straight-through, perforated 409 stainless steel tube for increased exhaust flow, surrounded by high-temperature sound absorption packing material which helps to deliver a deeper, mellower exhaust note. Their 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.

Superior corrosion resistance, good looks, and an economical price; unleash your beast with FlowMonster absorption mufflers. They are available in round or oval case shapes and different inlet/outlet configurations
