Josh, for what its worth. Im sure you know how much Torque helps in Autoxing. Im pretty sure a slightly more restrictive exhaust will yield significantly more Torque and only slightly less HP. And the torque is what really helps in when zipping around a tight course in a turbo charged car. I got 365 wtq with a el header, tbe, fuel pump, and spark plugs, tuned at 18 psi. But I sometimes over boost to about 23ish in the colder months. My whp was only 306 but Im not complaining, cuz it feels great!

If you are implying he pick up headers for the car, it won't be STU legal and that is what it looks like he is trying to stay legal in.

But I hear ya, I stopped autoxing and modded outside of the rules and now have 360tq, but no header yet.

To the OP, congrats on the car and glad to see your an avid autoxer. You should write up a small review on the differences in autoxing fwd to awd, if you have time.

Headers ARE legal in STU, I have the stock ones ported actually.

Thanks for the clarification, I thought they would throw you into SM.

I forget the wording exactly, but it mentions being able to replace the exhaust system, which in this case would included the headers.

Just arrived yesterday! These are 5Zigen FN01R-C's in 17x9 et43. In need of some rubber soon, still debating between the RE-11 and XS.


And also, I have dyno graphs. Directly below is the STU graph with the Street tune just below that. I'm looking to get the STU graph plotted against boost, at which point I will post as well.

5 spoke wheels look great on STi's. Nice choice.

Pretty good dyno #'s too.

Holy crap I love those wheels in matte black. How will the fitment be with the 9" width and 43 offset?

Fitment should be good, I'll let you know when I finally make a tire choice and get them mounted.
