*NOTE: This Pipe is 2.75" but can be used for 3" Inlet Turbos with slight modification*

We designed our inlet pipe for the 2008 STI with two goals in mind. Our primary goal was to make the pipe strong enough to resist sucking shut on even the largest of turbochargers.

The other was to make the largest pipe that could fit in the narrow space available for the 3" aftermarket inlet turbochargers. Why are we so concerned about strength? If your setup is stock, there is not much to worry about at all. But if you are running higher boost levels, or larger turbochargers, the turbo can literally suck the pipe shut and especially if you are still using the stock airbox. This situation is not only bad for power, but can literally destroy a turbocharger!

Is bigger better? Yes! If you are planning on making more power out of your turbocharged car, you need to flow more air, period. Bigger intercoolers, turbochargers, and exhaust systems will not work if you do not suck in enough air.

That is why we designed our inlet pipe so large. So even if you are running our big and beefy GTX55 turbocharger, you will not be let down before the air has even reached the turbocharger!
