Go Fast Bits Blow Off Valve Whistling Trumpet Low Boost Attachment Special Offer

Description

Upgrade your Subaru’s blow-off valve sound with the Go Fast Bits Blow Off Valve Whistling Trumpet Low Boost Attachment. Designed specifically for low boost applications, this trumpet attachment enhances the iconic whistle sound, making your ride stand out with a sharper, more noticeable tone. It’s ideal for enthusiasts who want a unique audio signature without compromising performance.

This modified version of the Whistling Trumpet works better than the standard 5701 on low boost setups, producing a higher pitch whistle at lower RPMs. Compatible with all GFB valves, it’s especially recommended for Respons and Deceptor Pro II valves, excluding models T9003 and T9503. To achieve the best whistling effect, ensure most of the air vents through the trumpet, as 50/50 venting may reduce the sound velocity.

Perfect for Subaru WRX, STI, and other turbocharged models, this attachment lets you customize your blow-off valve sound with ease. Enhance your forced induction setup and turn heads—shop this premium Subaru blow-off valve accessory at Subimods today.
