This blow off valve is ideal if you want the loud swoosh without your car stalling out or running rich! 
  
The Go Fast Bits TMS Response BOV vents to the intake & vents to the atmosphere with its dual port action. 
 
 
By utilizing a unique air diverting system, you can control exactly  how much air you dump to the atmosphere for noise, or the inlet for  silence. By sending the vented air back to the inlet (rather than  muffling it), there is no restriction and the valve still operates at  maximum efficiency.
  
 
 For cars with sensitive air flow meters such as the DSM, the valve  can be tuned to vent just enough air back to the inlet to prevent  backfiring while still giving the loudest possible blow-off noise. This  BOV is fully adjustable by the flip of your wrist.  
 TECH TIP: This is a 100% bolt on BOV for your DSM, no expensive flanges are required for installation.  Installation is very easy and will only take 10 minutes and can be done in your  driveway. The blow off valve provides a deep whoosh under heavy boost and is  fully adjustable with the flip of your wrist.
