Q & A

What's in the Box

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!

  • 100% T-304 stainless steel construction
  • Compact size fits all racing applications
  • Ultra lightweight - less that 1/2 lb. each
  • Little or no power loss
  • Easy bolt-in installation
  • Typically good for a 1-3 reduction in db 

Typically good for a 1-3 dB reduction.

Speedway does not currently offer a muffler for the lake style headers. However, we have had a few customer use the vortex insert cone muffler with the lake style headers but may require some slight fitting to work.

Is there any drilling required? It says "simple bolt-in installation". Does it just fit snugly inside the header pipe, just past the collector?

Depends how far into the collector you insert it. Should be a snug fit.

These slip in end of collector leaving about 1/2" from end. You can the weld in place or drill hole through collector and tab on cone and bolt in place
