The new IPD Y-Pipe delivers the same amazing proven performance as with the previous generation Turbo. Porsche made very few changes to the intake system from the 991 Turbo to the 991.2 Turbo. Ballistic acceleration and a top speed of over 200 mph places the new Turbo in a very elite class of supercars. But of course the IPD Y-Pipe (and Plenum) raise the performance bar even higher for Porsche driving enthusiasts who seek fighter jet performance from their German Turbo 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 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 dimpled interior surface cannot be achieved with conventional round tube construction.
The Y-Pipe is a direct bolt-on engine upgrade that requires no modifications but should be perform by an experienced Porsche technician familiar with the 991 platform. Y-Pipes comes with all the required hardware necessary to complete the installation.

Porsche 991.2 Turbo /S
Porsche GT2 RS
IPD took delivery of its 991.2 Turbo S and the R & D started the second it arrived at its new home. The new Turbo doesn't substantially benefit from any one particular upgrade, but the sum of its improvements deliver a superior overall Turbo compared to the already impressive 991.1 Turbo it replaces. Yes, we know the latest Turbo is faster with 20 more horsepower but it's the combination of lightening shifts, razor sharp handling and spiritual connection to the vehicle that elevates the driving experience of the extraordinary new 991.2 Turbo.
Porsche made a number of substantial upgrades with the latest 991.2 Turbo. Engine improvements include revised intake ports, larger injectors, higher volume fuel pump, larger turbo compressor wheels and more efficient intercoolers, but the factory intake system remained relatively unchanged allowing the IPD Plenum and Y-Pipe to fit with only minor modifications.
The 991.2 Turbo Plenum upgrade delivers staggering engine power and torque gains that will raise the performance bar of the already potent supercar as well as the hairs on your neck. Horsepower gains are found throughout the entire power band with the bulk of the gains being realized between the 3500-5000 RPM range. Max power gains of 45+ wheel HP come in at 4300 RPM and hold strong all the way to redline. Torque is even more impressive at 60+ in the midrange with a massive torque gains from 3500-5000 RPM.

The new 991.2 turbocharged Carrera Plenums are now available for new Carrera drivers looking to raise the performance bar of their 3.0L turbo engines. The Carrera Plenum is very similar to the Turbo Plenum with only minor modifications to the hardware package. No official testing has been conducted as of yet but based on past experience and customer feedback we expect power gains to be in the mid 30+ range and torque over 40. Stay tuned for dyno testing coming as soon as we get our hands on a test car.

Our brand new 991 Carbon Y-Pipes are designed and engineered to deliver substantial net horsepower and torque gains across both power curves, but without the weight penalty of cast aluminum construction. These lightweight Y-Pipes are inspired and modeled after our proven 991 Turbo Y-Pipes featuring slightly larger “non-round” runners and optimized merge collector areas that dramatically improve intake air flow and overall engine performance for both stock and highly modified Turbos.
In determining the scope of change for our next generation Y pipes we considered a multitude of materials, manufacturing processes, and shapes. In the end, we determined that by using a composite, we could achieve a reduced wall thicknesses without the penalty of casting shift. The result was more cross-sectional area and therefore more air flow. But we didn’t stop there. We sought out an experienced manufacturing partner with a background in pinnacle level motorsports and insisted on using the highest quality UV stable structural prepreg composite with an autoclave cure. Because the finish of the outside is important for hose fit and aesthetics, we built the parts with female tools. However, we didn’t want to compromise the internal geometry with typical folds and wrinkles found with a vacuum bag layup, so we invested in bladder tooling to ensure a uniform and smooth internal surface. The side benefit of this aerospace grade process and material was 75% less weight of the part which sits behind the axle center line making it an important contributor to the handling and dynamics of rear engine cars.
The superior design, materials and construction of our Carbon Y-Pipes deliver the same impressive gains of 40+ wheel HP and 50+ wheel TQ, but benefit from substantial weight reduction for Turbo clients who demand top tier level motorsport components and quality for their 991 Turbos and GT2RS’s.
Just like all IPD products, our 991 Carbon Turbo Y-Pipes are designed, manufactured, and assembled here in the USA.
The 991 Carbon Turbo Y-Pipes are a direct bolt-on engine upgrade that
require no modifications.
We strongly recommend that an experienced Porsche technician who is familiar with the 991 platform perform the installation.

do88 proudly presents the worlds first high flowing turbo inlet hoses for Porsche 991.1 / 991.2 Turbo. Self developed by do88 in Sweden !
• Much larger overall inner diameter for improved air flow, 31 % higher! (see graph diagram ). The hoses have a 2,5 inch (63mm) inner diameter at the narrowest location.
• Smooth flow transitions.
• Very smooth internal surface for best air flow.
• Excellent thermal properties, the hoses will not absorb heat from the engine.
• The hoses are reinforced with stainless steel wire to eliminate the risk of implosion on high out-takes.
It was a real challenge developing new turbo intake hoses for the 991 Turbo. The lack of space made it really difficult to make a set of hoses that would outflow the stock plastic pipes. We succeeded but in some smaller areas we had to compromise and allow these hoses to have no clearance, so they will push or rub in some non-sensitive areas.
Porsche 911 turbo. This immortal icon. The absolute essence of the motorworld´s cars, the Porsche 911, elevated by ten – applied with turbo charging. Could it get any better for a car enthusiast?
Owning a Porsche implicates more than just owning a car. A Porsche is a Porsche. You find yourself travelling in the true definition of immortality, feeling ever so alive. Owning a Porsche is all about enjoying every single detail there is to it. Everything ought to be as optimised and as refined as possible.
This is where do88 fit in. Our self-developed intake hoses increase air flow with 31 %. We can ensure you the sensation while driving is very different. The improvement in throttle response is immense, making the car feel so much more refined and alert. This upgrade makes it become what it should have been from the start. This is an improvement no test figures can explain, it has to be perceived behind the wheel of a 991 turbo!
The package includes everything for mounting:
• 2 wire-reinforced silicone hoses
• 2 silicone hoses
• 2 breather valves
• 2 CNC machined VTG adapters
• Clamps and Screws
This product is available in 2 options, OEM Porsche turbos or with 51.5mm turbo adapters for cars where the compressor wheel has been replaced, and compressor housing machined larger.

Water tank
An additional water tank for charge air cooling increases the standard volume by around 9 litres and ensures that the range is significantly extended between water refills.
As a result, this allows the intake air temperature to be cooled for longer, with the objective of achieving maximum power yield.
