TurboXS RFL Blow Off Valve - WRX 2008-2014 / Legacy GT 2005-2009 / STI 2004-2017
The TurboXS RFL Blow-Off Valve, or Really F'n Loud BOV, is designed specifically for the owner of a 2008-2014 WRX or 2004-2009 Legacy GT who wants an extremely loud, 100% vent-to-atmosphere blow-off valve.
This is the loudest valve on the market at 115 db at 15 psi. Not only does it's polished/anodized aluminum finish look and sound much better than the stock plastic bypass valve, the TurboXS RFL Blow-Off Valve adds function and can hold whatever massive boost pressure you want to run.
