Engine Modifications & Upgrades
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 "no-round" design with dimpled interior surface cannot be achieved with conventional round tube construction.
The 991 Turbo 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.

IPD Aluminum Intake Plenum.
Porsche 991 Carrera DFI 3.4L
The new 991 Carrera is arguably one of the sexiest Porsches to come out of Stuttgart in recent years. But like most Carreras, power output is controlled to meet a "performance target" that satisfies the masses and not the dedicated Porsche driving enthusiasts. IPD is here to scratch that proverbial performance itch for those Porsche drivers looking to elevate the already visceral Porsche driving experience to the next level.
The engine in the new 991 remains relatively unchanged from the previous 997.2 Carrera. The 991 Carrera continues to employs the 82mm throttle body just like the Carrera before it. This means there is no "Competition Plenum" available since the 82mm TB is still the largest TB available from Porsche.
Performance gains remain at 14+ horsepower at the wheels. As with most IPD Plenums, the bulk of the power gains are realized in the mid-range where they are most used and enjoyed. Unlike other mods, the IPD Plenums deliver net power gains across the entire rev range.

The new 991 IPD Turbo Plenum is nearly identical to the previous 997.2 Turbo Plenums. The new IPD Turbo Plenum is offered in one single 74mm version which utilizes the factory 74mm throttle body. The 991 Turbo intake manifolds are smaller than the 997.1 Turbo manifolds which is great for improved boost response and gas mileage but less than ideal for making substantial power gains. The 74mm TB provides more than adequate flow for these more restrictive intake runners eliminating the need for a larger 82mm "Competition" version.
The already explosive power of the 991 Turbo can be further increased with the new 991 Turbo IPD Intake Plenum. The patented IPD Plenum design works exceptionally well with all forced induction applications and the 991 Turbo is no exception. Power and torque increases provided by the IPD plenum are impressive and stay well above all factory power curves from launch to redline. Maximum power increases take place in the midrange where it's most needed, most critical and most enjoyed.
The 991 Turbo plenums deliver smooth and linear power with considerably quicker boost response creating a longer and more desirable power band. The Turbo plenums deliver reliable performance for both street and motorsport applications enhancing the already visceral Porsche Turbo driving experience.
The 991 Turbo requires an "adaptation" period that can be fully realized with either a series of hard pulls on the dyno or a series of spirited driving sessions, which of course IPD recommends only be performed on a closed course circuit. Installation of all Turbo Plenums is highly recommended to be performed by qualified and trained Porsche technicians.

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 pre-preg 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.
