IPD High Flow Carbon Fiber Y-Pipe for 991 Turbo / Turbo S

IPD's new Carbon Y-Pipes are engineered to deliver significant net horsepower and torque gains across both power curves, while offering a substantial weight reduction compared to cast aluminum alternatives. Inspired by IPD's proven 991 Turbo Y-Pipes, these lightweight carbon fiber units feature slightly larger "non-round" runners and optimized merge collector areas. This design dramatically improves intake airflow and overall engine performance for both stock and highly modified 991 Turbos.

Utilizing carbon fiber construction allowed IPD to minimize wall thickness and maximize the use of available space, resulting in increased cross-sectional area and greater airflow. To ensure the highest quality, IPD partnered with pinnacle-level motorsports, employing top-tier UV stable structural prepreg composite with an autoclave cure. Female tooling was used for a superior external finish, crucial for hose fit and aesthetics. Furthermore, IPD invested in bladder tooling to guarantee a uniform and smooth internal surface, avoiding the typical folds and wrinkles associated with vacuum bag layups, thus optimizing internal geometry. This aerospace-grade process and material also yielded a remarkable 75% weight reduction for a component located behind the axle centerline, making a notable contribution to the handling and dynamics of rear-engine vehicles.

The superior design, materials, and construction of IPD’s Carbon Y-Pipes deliver the same impressive gains of 40+ wheel HP and 50+ wheel TQ as their aluminum counterparts, with the added benefit of significant weight savings for 991 Turbo owners who demand top-tier motorsport components and quality. This Y-Pipe is a direct bolt-on engine upgrade requiring no modifications. Professional installation by an experienced Porsche technician familiar with the 991 platform is strongly recommended. Purpose: Significantly improves intake airflow, resulting in substantial horsepower and torque gains, along with a significant reduction in weight for enhanced performance and handling.
