Default STi Uppipe in the Legacy GT

I installed a STi uppipe in my Legacy. The change in response is amazing it cuts the lag by a 60% or more (butt dyno). I really recommend this as a first mod. Here some pics.

Here the OEM uppipe look at the cat (ugly).


Here the STi uppipe free of any interference


Side by side comparison note that the STi uppipe doesn't have the sensor bung.


Installing the uppipe...


Resistor to eliminate any CEL problem


Here is where the resistor is inserted

I did this in the dealer where I bought the car. The guy in the photo is one of the mechanics.

The dealer did that for you? That's cool! I wonder if mine would. How much for the pipe and labour?

Now...is the catch the fact that it was an STI uppipe therefore the dealer was glad to install or would they have done it if it was a Helix or Perrin uppipe?

They have other uppipes in stock. I chose the STi for the OEM look.

there was some sort of airflow sensor in the stock setup, where the sti part had no sensor. i'd assume the resistor tricks the 'computer' in to thinking the sensor is there and functional even though it isn't..

Nice! Glad to hear it makes a difference in tubo lag because I can definitely feel it in my LGT.
I'm about to put up a WTB thread for a used sti up pipe for a swap into my '06 legacy gt. Any reason why I should hold off and save more $ for an aftermarket Perrin or TurboXS??
