With the success of our VR825 kit on the Porsche 997TT, we revisited the 996 Turbo to see how we could make more bolt on performance.  Opening up the air flow of the intercooler pipe system is one way we achieved this on the 997TT.  So Agency Power set out to build a OEM replacement 3inch Y-Pipe that would work with the stock intercooler fittings and throttle body.  To begin the process, we got one of our customers modified 996 TT to the shop.  This car was already equipped with upgraded GT2860 turbos and all the trimmings to go along with it.  What it did have is stock GT2 intercoolers and a stock throttle body and plenum.  The development process was simple…  Build a product that would retain the stock airbox, flow better, use OEM parts, and look the part!  Our fabrication team begin building the product on the car using 6061 aluminum and basically building each piece on the vehicle.  Once completed, we had a finished part that was then powdercoated and ready for testing.  Since t HERE was no additional length added to the system compared to stock, we decided not to pressure drop test the system because of the complexity.  Pressure drop is usually a concern on cars such as the STI when you go from the factory top mount intercooler to a front mount intercooler adding feet of intercooler piping.  Based upon the dyno results, the cars spool did not change.

Using our Mustang all wheel drive dyno, this car came to us with a tank of 91 octane and low boost set at 1.2bar.  With fans moving fresh air to the intercoolers, we did a baseline on the car and achieved a starting point of 493whp and 477ft/lbs of torque.  Leaving the car strapped to the dyno, we removed the stock Y-Pipe and bolted on the fresh red Agency Power upgrade connecting to the F-Hose.  The new Y-Pipe gets rid of 70% of the stock boost hose length and reduces the bend by about 45 degrees for a straight shot to the intercooler.  For those running stock style intercoolers, a reducing coupler is supplied with a shorter fitting to clip into the intercooler end.  For those customers wanting maximum efficiency, we supply a 3inch piece of aluminum and a coupler to be welded to aftermarket endtanks.  With everything secured in place, we fired up the car to give it a run with the new Y-Pipe.  With absolutely NO changes to the cars configuration, the Y-Pipe added 21whp and 24ft/lbs of torque to the car.  This was quite an impressive bolt on gain that also added style and potential scalable performance to the car.

This part fits all 2001-2005 Porsche 996 Turbo, X50, and GT2.  The part has several options available.  Please select carefully.
