Porsche High Flow Y-Pipe - IPD 91500.2-GT2

IPD GT2 RS Y-Pipe features an accentuated merge collector area that allows the intake air flows from each intercooler to meet in a more parallel fashion as air enters the throttle body, minimizing turbulence and increasing boost response. The combination of the Plenum and the Y-Pipe will deliver substantial power and torque gains guaranteed to transform your Porsche driving experience.

The IPD Y-Pipe (and Plenum) raise the performance bar even higher for Porsche driving enthusiasts who seek fighter jet performance from their German 911 missiles.

IPD invested countless hours of R&D with a variety of unique design features and multiple prototype tests before settling on an optimum design that significantly improves engine performance for both stock and highly modified 991 Turbos. Our innovative Y-Pipe design is not only larger but also utilizes “non-round” runners, an optimized merge collector area and our proven dimpled interior surfacing. This superior design delivers a greater volume of air, improved laminar flow and increased air velocity. These improvements deliver an additional 40+ wheel HP, 50+ lb/ft of Torque, improved boost response and more linear power and torque curves.

As we all know, bigger is not always better when it comes to forced induction applications. The IPD Y-Pipe is considerably larger than the factory but not so large as to cause pressure drop within the intake tract resulting in turbo lag and reduced performance. This optimized “non-round” design with dimpled interior surface cannot be achieved with conventional round tube construction.

The 991 TGT2 RS Y-Pipe is a direct bolt-on engine upgrade that requires no modifications but should be performed by an experienced Porsche technician familiar with the 991 platform. Y-Pipes comes with all the required hardware necessary to complete the installation.
