VTA T9451 DV+ Performance Diverter Valve

VTA T9451 DV+ Performance Diverter Valve – Blow Off Valve Sound Upgrade

Unlock sharper response and an aggressive blow-off valve sound with the GFB DV+ T9451 VTA upgrade. Designed to replace the weak factory diverter valve internals, this performance-focused solution delivers faster throttle response, improved boost holding, and a louder vent-to-atmosphere (VTA) sound where applicable.

Unlike traditional full replacement valves, the DV+ retains the factory solenoid for lightning-fast ECU control, while upgrading the valve mechanism to a precision-machined metal piston system. The result is improved reliability, stronger boost control, and a more responsive turbo system under load.

Whether you want improved performance, enhanced turbo sound, or both, the T9451 DV+ delivers a simple bolt-on upgrade with proven results.

Key Features:

• Improves throttle response and boost recovery
• Stronger boost holding under high load and tuned engines
• Retains factory ECU-controlled solenoid for OEM-level response
• Precision-machined metal internals replace weak plastic components
• Optional vent-to-atmosphere (VTA) sound depending on setup
• Direct bolt-on installation – no major modifications required
