If you were following our Porsche Panamera Turbo build with our Agency Power exhaust, you might have seen the prototype Y-Pipe we built and dyno tested. Looking at the stock Y design in front of the throttle body, we knew there were improvements to be made.

This throttle body is the same size as the Cayenne TT throttle body we use on our 996TT and 997TT upgrade kits. The stock Y-Pipe is a 2 piece plastic Y design that is smooth on the inside with a “deflector” internally to channel air. The bad part about the stock one is it goes from a 78mm ID at the throttle body down to a approximately 51mm diameter Y split. This then connects to rubber boost hoses that expand under pressure. Both of these are power robbers! If you retain the stock design and stock diameter hoses, YOU CANNOT GAIN power no matter if the YPipe is cast aluminum or plastic. This is why we made a complete Y-Pipe kit which retains a 3inch aluminum design all the way to the factory end piece connections at the intercoolers.

The dyno sheet shows the car in standard mode with the stock Y piece versus our big Y-Pipe kit. There are huge gains throughout the ENTIRE rpm band which is impressive. Dyno proven results are not something to see, but something you can feel. The more airflow you get into the throttle body, the more HP you will gain. By eliminating the rubber boost hoses, you remove the pressure fluctuation from expansion, which loses power. With our Y-Pipe kit, the air flow improvement improves every aspect of driving your Panamera Turbo. As tested on our Mustang AWD Dyno, the Y-Pipe made 34awhp and 35ft/lbs of torque.

These Y-Pipes are all made in the USA from 6061 heat treated aluminum that is TIG welded in JIGs for a perfect fit. The Y-Pipe includes necessary couplers and clamps for a true bolt on installation. The kits come standard in gloss red or gloss black, but can be done in any customer color at no charge. These are designed for the 2010 and up Porsche Panamera Turbo.
