Description

Unleash your exhaust beast with FlowMonster 2-chamber mufflers. These chambered mufflers create an aggressive exhaust note, giving a powerful voice to your car, truck, or SUV.

The 2-chambered internal design cancels out unwanted high-pitch frequencies, with no packing—producing an aggressive exhaust note that will not change with time. FlowMonster 2-chamber mufflers are coated with high heat-resistant silver paint for a clean look under your car. Hear the roar with FlowMonster!
