Simply screw this trumpet into any Deceptor Pro, Stealth FX or WRX Hybrid (updated version only), and it will produce an aggressive whistle that sets your car apart from others. Note: definitely does not work on the ‘Universal’ Hybrid, Liberty GT Hybrid, or any other GFB blow-off valve.
There are a few conditions that must be fulfilled to get the most out of this product. Your blow-off valve should be set to full atmosphere venting, and boost must be at least 12 psi (0.81 bar). The whistle noise is dependent on air velocity through the trumpet, and low-boost set-ups will not be effective.
This trumpet is for the Deceptor Pro, Stealth FX and WRX Hybrid. It definitely does not work on the ‘Universal’ Hybrid (1003), Liberty GT Hybrid (1015), or any other GFB blow-off valve.
