Info

The Vortex¬ģ Turn Down is expanded to slip over the collector outlet or tailpipe.¬† Greater sound reduction can be achieved by directing the outlet away from meter or sound test point.¬† U-tab mounting hardware is included.

  • Vortex¬ģ Insert Cone features T-304 stainless steel construction
  • Mild steel housing
  • Compact size fits all racing applications
  • Ultra lightweight - less than 1/2 lb. each (cone)
  • Little or no power loss
  • Easy bolt-in installation
  • Turn down with insert cone available in 3-1/2" diameter¬†

How it works: The  installed near the exit of the header collector or muffler outlet provides a large friction area to reflect and dissipate sound energy, thus reducing the dB level.  The open area of the cone is actually greater than the area of the collector or exhaust pipe, thus reducing a back pressure condition.  Because no significant back pressure has been introduced, the engine is still able to use the scavenge ability of a good header to create horsepower and torque.  Dyno and track tested show significant noise reduction with little or no power loss.

Some parts are not legal for use in California or other states with similar laws/regulations
