Performance high flow Y-Pipe. Porsche 997.1 Turbo 07-09  ❭  TR-140

Extreme high flow performance Y-Pipe.



To Fit:
Porsche 997.1 Turbo models 2007-2009

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 do88 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!
