Let's face it; open exhaust is a thing of the past! Sound requirements, mandatory mufflers, or maximum db level are found in all forms of racing today. From Mini-Stock to Outlaw Sprint Cars, reducing the sound level is becoming the norm. Today's racers are spending thousands of dollars to go racing. The last thing they want to do is get put on the trailer for too much noise. The Vortex Insert Cone can help you keep on track. That's sound insurance!
