Description
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+ Foot Pounds 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 a dimpled interior surface cannot be achieved with conventional round tube construction.
The 991 GT2 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.
This is a 991 GT2 RS-specific unit.
