Blow Off Valve Sound - Bypass Valve Driveability

Love that awesome Blow Off Valve sound but hate the backfiring and stumbling that can sometimes happen on Mass Airflow metered cars like EVOs and WRX/STi's when using full vent to atmosphere BOVs?

TurboXS has the solution. The new TurboXS Hybrid BOV gives you stock-like driveability during light throttle driving AND that awesome BOV sound you want when you're hammering on the throttle and banging through the gears.
