The revolutionary 997.1 and 997.2 Turbo IPD Y-Pipe were designed and engineered for Turbo driving enthusiasts who desire improved performance for both stock AND highly modified Turbos without sacrificing reliability. The new 997.2 Turbo Y-Pipe is not a cast reproduction of the factory Y-Pipe but a complete re-design from scratch, that delivers performance through superior design and efficiency. The IPD Y-Pipe increases air flow while decreasing air turbulence making it an intelligent performance upgrade for any 997 Turbo Porsche.
The factory Y-Pipe is slightly more restrictive and becomes a weak link in the engine performance chain when factory power and torque levels are exceeded, making the IPD Y-Pipe a required performance upgrade. The IPD Y-Pipe has larger inlets and an optimized diversion area allowing for even greater power gains. This superior and more efficient IPD design flows 126 more cfm (cubic feet per minute) than the factory Y-Pipe helping elevate the already potent Turbo engine. The IPD Y-Pipe develops 15-20 additional wheel horsepower and works exceptionally well when combined with either the 74mm or Competition 82mm IPD Plenums.
As with any other performance mod (especially for turbo applications), bigger isn't always better, especially for street applications. The IPD Y-Pipe has been optimized to deliver solid performance gains without being so large causing a drop in pressure inside the intake tract. Just like the Plenums (but in reverse), the Y-Pipe channels the air flow more effectively. Although the larger runners help contribute to the performance gains, the bulk of the performance improvements come from the exaggerated merge collector area that directs the inlet air traveling from the left and right intercoolers to run more parallel as airflow meets and enters the throttle body.
The IPD Y-Pipes can also be an aesthetic piece of engine eye candy when ordered powder coated or polished. Y-Pipes can be powder coated in virtually any color imaginable. Whether you're looking to match your calipers, body color or creating a custom engine bay accent. Ceramic dispersement coatings can also be applied to further improve performance. The IPD 997 Turbo Y-Pipes are designed to be a direct replacement of the factory OEM Y Pipe. There are no modifications or fabrication required for installing the IPD Y-Pipe. This is an easy and straight forward R & R (remove and reinstall) bolt on upgrade.

IPD has been testing and developing a new 82mm Competition version Plenum for modified 996 and 997.1 Carreras. The larger 82mm throttle body, from the 997 GT3, has a 22.8% increase in cross sectional area allowing for considerably more air flow into the Plenum and ultimately inside the combustion chambers for increased performance. IPD has a wide variety of "Competition" Plenums, all which utilize larger throttle bodies, but never one for the Carreras, until now. The bulk of power and torque gains come from the patented "Y" designed Plenum (with factory OE size TB) but Porsches with additional performance mods can realize even more power with the larger Plenum and TB.
Initial prototype Plenum tests have been conducted by Shahin Mobine of RennTrack.com on his highly modified 997 Carrera S. The 997 S started life as a street car, but has become an extension of Shahin's persona, and is now a dedicated track car focused on dominating the Owners Club Race Class in the POC. The RennTrack.com / HRG #393 is fully modified to Race Specs Race Series which requires all cars to compete at a GT3 Horsepower to Weight ratio to ensure tight competition and prevent skyrocketing costs.
The car finished 2nd place overall in the GT3 class driver championship after only competing in less than half of the season. The RennTrack.com / HRG #393 claimed 2 first places, 3 second places and 3 third place finishes. The car ran and finished ahead of many 996 and 997 factory-motorsport Porsche Cup Cars. The 997 S will be campaigned in the same series for 2012, seeking an overall GT3 championship.
Shahin said, "Since we race in a HP/Weight class, we are always looking for a way to develop the car further to make it faster. After looking at the car we decided we could improve the stock intake system to bring in more air to the engine at a faster and smoother rate. I put a call in to Greg at IPD and discussed a few options. After explaining to him more about our car and our plans we both decided to move forward with a brand new prototype Competition Plenum that IPD was developing for more modified cars like our race car."
"The car's engine is equipped with a custom 997 C2S race intake, Lucas Fabrication headers, Lucas Fabrication Cat-Bypass race exhaust, IPD 997 3.8 Competition Plenum, Porsche 997 GT3 Throttle Body and BMC replacement air filter."
Shahin continued to expand, "Together the new plenum and larger 997 GT3 throttle body would help our engine get a larger volume of cold air from our ram air decklid, allowing the engine to work even more efficiently and produce even more power. After Hergesheimer Motorsports installed the IPD plenum and 997 GT3 throttle body, the cars sounded instantly meaner! We all looked at each other and smiled. "She sounds like she is reving faster and the exhaust sounds deeper, you can even hear the air box more!"
"We loaded the car into the trailer and off to the track. After a few laps, the car just seemed more peppy, it would accelerate and pull more quickly, shifts points slightly changed and I found myself shifting sooner before hitting redline than previous times at the track. Overall I could not be happier with the results, the car sounds, and feels better and at the end of the weekend our lap times in the car were the fastest the car has run at Willow Springs. Big thanks to Greg and the whole IPD crew for letting us test the new 82mm prototype Plenum and for providing such a great product and even better service."
