GFB’s DVX Takes The Extremely Popular DV+ Diverter Valve And Adds Dual Venting Outlets Along With Our Patented Venting Bias Adjustment System. So Not Only Do You Get IMPROVED BOOST HOLDING And THROTTLE RESPONSE, You Have Total Control Over Your BLOW-OFF SOUND VOLUME!

What Makes Dvx Different To Any Other Valve That Goes “whoosh”?

• The DVX is not just a noise maker (like BOV spacers) – by modifying the valve operation method it offers the same PERFORMANCE BENEFITS that the DV+ does.

• It retains ECU CONTROL for the fastest possible operation.

• No other blow off valve has the advantage of GFB’s Venting Bias Adjustment, allowing you to alter the blow off sound simply by moving the adjustment lever.

• Built to last.
