A WORLD FIRST in blow-off valve technology, the Deceptor Pro is based
on the patented volume adjustable Stealth FX blow-off valve, but
advances the design even further, featuring an industry world first:
electronic proportional in-car adjustment of blow-off valve volume! It
is no longer possible to cruise the street with a permanently noisy
blow-off valve - the Deceptor Pro lets you choose when and where you
are noticed!
