Although the 991 Turbo Plenum is very similar to the previous 997.2 Turbo Plenum, the Y-Pipes are completely different from each other. IPD is currently performing all the R & D and will be engineering the best possible Y-Pipe that will feature many new IPD innovations. As with any Turbo application, bigger isn't always better and the goal is to always develop a Y-Pipe that delivers optimum flow and air velocity without being too large causing pressure drop, loss in boost response and ultimately performance.
The 991 Turbo IPD Y-Pipe will be designed to deliver more power and torque from the already potent 991 Porsche Turbo. This will not be a cast reproduction of the factory Y pipe but a complete re-design from scratch, developed to deliver even greater air flow for both stock AND highly modified Turbos.
The factory Y-Pipe becomes restrictive when adding substantial power gains. This superior and more efficient design flows more cfm and reduces turbulent air flow as it enters the throttle body. The IPD Y-Pipes typical have larger inlets and an optimized diversion area that allows for impressive power gains. Of course the new 991 Turbo Y-Pipe will be a direct bolt in replacement that will not require any modifications or fabrication.
We will post and upload all the latest news related to the development of the new 991 Turbo Y-Pipe as we continue the R & D process.
