The perfect compliments to Fabspeed's exhaust upgrades, this high performance intake plenum and y-pipe from Innovative Pro Design provides substantial power gains by increasing the efficiency and flow of the engine's air intake system.
COMPATIBILITY:
Fits all Porsche 991.2 GT2 RS vehicles (2018+)
FEATURES:
IPD Plenum
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 GT2 RS 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 mid-range with a massive torque gains from 3500-5000 RPM.
The 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.
IPD Y-Pipe
The new Turbo 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. 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 “no-round” design with dimpled interior surface cannot be achieved with conventional round tube construction.
The 991.2 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.
The 991.2 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.
Design Notes
Superior and more efficient design over the factory intake.
The IPD Plenums are products of efficiency that simply improve intake air flow and increase air velocity. The “Y” shape design and dimpled interior surface make air flow more laminar (less turbulent) dramatically improving power and torque across the entire RPM band. Smoother more optimized intake air flow will improve the performance of any engines. The more efficiently an engine breaths, the more efficiently it produces power.
Deliver impressive power gains regardless of modifications.
The superior design of the IPD Plenums optimize flow while increasing air velocity. Period! This applies to any Porsche engine, producing any level of power. The patented “Y” design delivers impressive performance gains for both bone-stock and highly modified Porsches. The more efficient design of the IPD Plenum will always outperform the factory air distributor. The factory intake will become even more detrimental to performance as your increase the power and torque outputs. The bigger the power, the better the IPD Plenum performs.
Produce substantial gains for both turbo and NA applications.
The Plenums always deliver considerable gains on both turbo AND naturally aspirated engines. It's a fact that the Turbo Plenums do produce more power than the NA Plenums. But the Turbo engines also produce more power. The fact is that the percentage gains of the different Plenum applications are actually almost identical, around 8-10% depending on the specific model.
Do not require an ECU flash and will not cause a CEL.
IPD Plenums should never cause a CEL or require an ECU Flash. If a Plenum is installed correctly there should be no fault codes or running issues, only solid performance gains across the entire RPM band. The only issue that could possibly arise is the need for a new MAF sensor if you already have a degraded sensor or perform a TB adaptation. There is absolutely no need to re-flash your ECU after installing an IPD Plenum, Period! Although any reputable Porsche tuner could further optimize an ECU program to achieve even greater performance gains with the Plenum installed.
Aluminum Plenums run cooler and don't suffer from heat soak.
The Aluminum Plenums do NOT experience heat soak under driving or racing conditions. It is true that aluminum has a higher thermal conductivity than plastic. In fact, aluminum is 650 times more thermally conductive than plastic and has a specific heat capacity that is 550 times higher than plastic. This means the aluminum Plenum actually spreads the energy it's exposed to 656 times faster than the plastic and can store more than 550 times the amount of energy per unit mass. Bottom line, aluminum can absorb more heat than plastic, but it also takes considerably more energy to heat up and it's losing that energy way faster than the aluminum allowing the IPD Plenum to remain cooler from outside ambient air under driving conditions, ultimately improving engine performance over plastic. Plus, why would Porsche utilize aluminum intakes on GT3's, GT2's, Cup Cars and Cup R's?
NOTE: If you are upgrading your throttle body along with the IPD Plenum, you may need to visit a dealership to have them perform a manual throttle body adaptation process. Some customers have reported that installing the throttle body and plenum while the battery is disconnected results in the car performing an adaptation check once the battery is reconnected, alleviating the need to visit a dealership. However, Fabspeed recommends having the adaptation performed at a certified dealership for optimal results. If you need a recommendation for a dealership in your area, please contact us.

Just got my Fabspeed Maxflo Mufflers installed on my BMW E90 M3! Could not be happier. I have a fully catless setup, and had trouble finding a suitable rear section that would bring the car to reasonable volume levels, reduce drone, and cut down on the inherent "raspiness" of the S65. This exhaust ticks all the boxes! The volume level is surprisingly tame for the car being fully catless, but certainly louder than the stock rear section. In-cabin noise or "drone" while cruising is greatly reduced compared to the muffler delete I was running previously. Exhaust is absolutely perfect for a daily driver. The "rasp" is just right as well. Sounds incredible on the downshifts. Power and low end torque, surprisingly enough, increased greatly. I keep getting compliments from people at car shows, gas stations, and even at stoplights. Fabspeed was an excellent company to deal with as well. The owner Joe Fabiani is a stand up guy, and scheduled me in super early on a Wednesday morning so I could make a business meeting later in the day. The service was fast and professional, and their tech Dustin walked me through the exhaust setup on my car, and allowed me to customize my choice of tips, and assure their placement is perfectly to my liking. I've read some distasteful reviews of Fabspeed as of late, but the majority of them are frankly not true. I am a former employee of the company, and have seen all the ins and outs of the sales team and fabrication facility. There is nothing out of the ordinary to see, and they will give any walk in customer a full tour of the facility showing off the cool equipment that they have to produce their systems. The recent slew of slander and distasteful reviews stem from one customer who tracked his car with a Fabspeed product not designed for the track, voided his warranty, and was stuck with the product. Fabspeed eventually made the situation right, but this customer has a reputation for slandering other businesses and throwing them under the bus for his own personal gain. It is painful to watch a company such as Fabspeed have to endure something like this, hence why I feel the need to address it in this review. Overall, great friendly service, awesome product, cool facility, and one AMAZING sound!
Welcome to the jungle! My C8 Corvette with Fabspeed sport cats, full exhaust is unmatched in the game! Compliments everyday I take it out! Couldn’t be happier with the craftsmanship and service from Fabspeed Sports thank you!!!!
months before i put down my deposit on my custom ordered P car, i already knew which exhaust was going on it. even though there weren't any youtube vids of the system, i relied on the opinion of the Fabspeed employee and other forum members who had the system on their cars to tell me the characteristics of the exhaust. so, when there was a Father's Day sale, i pounced on it and had the exhaust sitting in my living room several weeks before i took delivery of my car. craftsmanship on the macan turbo slip system is flawless. no damage during shipping transit, either. the CF tips look awesome. install, done by a specialty shop near me, was done within 1.5 hours. system sounds exactly how i wanted it to sound; loud, pops, bangs, burbles, etc., etc. i even ordered some extra decals and they were kind enough to not charge me for shipping! now that's customer service.
These people really know what they're talking about. I spoke on the phone with Phil a few days ago for more information on the M3 Valvetronic system. He answered all of my questions, and yesterday I received my system. I dropped off my car to the shop this morning, and I just drove it home. There were no issues with install, and my car has become an entirely new beast. Thank you Fabspeed!
I had heard great things about Fabspeed from others in the industry but my expectations were definitely exceeded with this project. The team at Fabspeed went above and beyond when developing and building the exhaust system for our NSX. With the pictures and video commentary, they made us feel like we were a part of the action and that isn’t an easy to do when you are 800kms away and in another country. I know that there were many skilled hands that were involved with making this project come to life and I would like to extend our thanks to the entire team. Moreover, I’d like to take a minute to emphasize how much I appreciated having Alec quarterback this engagement. He was a key part in making this happen and was patient, professional, and extremely responsive at all hours of the day/night. The NSX was greatly missed while it was gone but it came back with a new set of lungs and the sound is much more fitting of a car in its class. We are already considering working with them on another project and I would highly recommend them.
