Moroso Spiral Flow Stainless Steel Racing Mufflers

4.0 out of 5 stars 8 Customer Reviews

Using advanced gas dynamics and sophisticated noise cancellation acoustics, Moroso engineers have developed these Spiral Flow stainless steel racing mufflers. The specially engineered spiral baffles that are wrapped around a "straight-through" core divide the exhaust flow into two separate paths. This significantly reduces noise levels with minimal effect on the backpressure. They have a round tube case with centered inlets and outlets, and feature polished stainless steel construction for the ultimate in durability.
