Moroso Spiral Flow Racing Mufflers

4.57 out of 5 stars 54 Customer Reviews

Using advanced gas dynamics and sophisticated noise cancellation acoustics, Moroso engineers have developed these Spiral Flow 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 all-steel construction for durability.
