High Flow Y-Pipe


- Porsche 997 MKII Turbo 2009>>

he incredible 997 Porsche Turbo is the most revolutionary and capable Porsche Turbo to ever come out of Germany. The already explosive power can be further increased with the new 997 Turbo IPD Intake Plenums.
The patented IPD Plenum design works exceptionally well with all forced induction applications and the 997 Turbo is no exception. Power and torque increases provided by the IPD plenum are impressive and stay over and above all factory power curves from launch to redline. Maximum power increases take place in the midrange where it's most needed and most critical.
Maximum horsepower gains range from 30 to 35 depending on vehicle condition and pre-existing mods. The 997 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.
Unlike the 996 Turbo the 997 Turbo requires an "adaptation" period that can be fully realized with either a series of hard pulls on the dyno or 10 to 50 miles of hard driving which of course IPD recommends only be performed on a closed circuit race track.
The 997 Turbo has an extremely sensitive ECU/DME making it prone to external environmental corrections so it is imperative that proper, adequate and consistent cooling be available when you dyno any of the 997 Turbos to get accurate and reliable dyno figures both before and after each test.
Installation of all Turbo Plenums is highly recommended to be performed by qualified and trained Porsche technicians.
Turbo customers looking to increase engine power without pushing the motorsport envelope to redline would best benefit from the 74mm IPD Turbo Plenum.
This version of the 997 Turbo plenum utilizes the factory 74mm throttle body and delivers impressive performance gains for both stock and slightly modified Turbos with exhaust and software.
The 74mm IPD Turbo Plenum is also designed to perform with the higher flowing IPD "Y" Pipe.

At 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; here is the result of our conclusions and development process!
Significant advantages with Do88's Y-pipe compared to the OEM pipe:
• Much larger inner diameter for improved air flow, do88 62% higher!
• 70mm mandrel bent aluminium pipes.
• Smooth flow cast collector part.
• Smooth internal surface for best air flow.
• Comes with high quality silicone hoses and accessories for installation.
• See enlarged images for more information!
Our pipe has both a very good flow rate and a low weight which is achieved by combining mandrel bent lightweight pipes with a high quality 3D freeform designed cast joint between them. Onto the cast part we then welded CNC-machined connections for bov and breather hoses.This construction adds a lot of performance but only small amount of extra weight. Do88 Performance Y-pipe weight 1,52 kg (3,35 lb) OEM plastic pipe weight 1,38 kg (3,04 lb) and a competitors cast performance pipe weight 2,76kg (6,08 lb)!
The pipes are then finished in a high quality powder coat that makes them look as good as they perform! You can choose between the more discrete semi gloss black and a fresh silver metallic finish.
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 62% increased flow at the same pressure drop! On our final tests of this Y-pipe together with our intercoolers on a Stage 1 tuned 997.2 Turbo PDK we measured a great performance increase. In all tests the car was driven in Sport Plus, automatic gear change and AC off. From our five in a row full throttle accelerations between 40-270 km/h (25-168 mph) we have very accurate and consistent test data for the range 50-250 km/h (31-155 mph). When analyzing the numbers, we found that we cut down the acceleration time for 50-250 km/h (31-155 mph) by 3 seconds!
Included parts in this kit:
• Full aluminium performance Y-pipe
• Silicone hoses
• Hose clamps
• Hose adaptors if the Y-pipe will be installed together with OEM intercoolers
