Part #: GS355BPV GS355BPV - Gothspeed Bypass Valve


This bypass valve was designed as a direct OE retrofit for the Ferrari F355 and F50, no other parts needed. This new valve design will quietly and reliably perform OE exhaust gas switching responsibilities. It also utilizes a genuine Pierburg vacuum actuator for seamless operation with the OE vacuum system.

The new bypass valve 'action' has been pre-tuned and needs NO adjustments.  The new valve should be handled with great care, especially during the installation process.  Installation should be performed by a skilled Ferrari technician... or, as a second-resort an owner whom is experienced in the installation and removal of the:  intake air boxes, MAF, heat shield, and exhaust components.

This is a direct fit replacement for Ferrari part 155006
