IPD Carbon Intake Plenum High Flow Y Pipe. Porsche 991.1 turbo / turbo S
- Porsche 991 Turbo 3.8L (520bhp)
- Porsche 991 Turbo S 3.8L (560Bhp)
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 are proud to present our newly developed Y-pipe kit for 991 Turbos - With this extreme high flow Y-pipe kit the performance of your 991 will increase!
From do88:
In the beginning of the development process of this product we spent a lot of time thinking what would be the preferred way to build a Y-pipe and here is the result of our conclusions and development process.
Our pipe has both a very good flow rate and a low weight which is accommodated by composing mandrel bent lightweight pipes with a high quality 3D freeform designed cast joint between them. Onto the cast part we then weld CNC-machined connections for bov and breather hoses. This construction technique adds a lot of performance but only a touch of extra weight. The pipes are then finished in a high quality powder coat that makes them look as good as they perform!
The kit also includes 2 high quality custom designed silicone hoses which are available in two different versions. Which version you need depends on if you will install the y-pipe together with the OEM intercoolers or the do88 performance intercoolers.
When it comes to air flow performance our Y-pipe totally outperforms the OEM Y-pipe by 58% increased flow at the same pressure drop! Be aware of that the OEM parts are only designed for the power level the car was built for originally. A power increase may cause your stock Y pipe to hold back the power of your engine. So even on an engine with a software tune only the do88 performance Y-pipe will give a performance increase over the OEM Y-pipe!
• Much larger inner diameter for improved air flow, 58 % higher! (see graph images).
• Made of 2,5" (63mm) mandrel bent aluminium pipes.
• The pipe has two methanol injection connections (1/8 -27 NPT). The pipe is delivered with blanking plugs in these connections.
• Smooth flow cast collector part.
• Smooth internal surface for best air flow.
• Comes with high quality silicone hoses and accessories for installation.
The do88 performance Y-pipe comes as a complete package with all parts necessary for installation.
Included parts in this kit:
• Full aluminium performance Y-pipe
• Silicone hoses
• Hose clamps
When you order this kit, there is one choice that has to be made: Please select below which intercoolers you have on your car. OEM Porsche or do88 Performance intercoolers.
