Follow up: I got my IC set up today... FINALLY (slow shippers). I bought the SM elbow and longer 2.75" coupler for TB. I ended up chopping off a good 3" or so from both arms on the elbow; the 4.18" elbow I referenced earlier probably would have worked fine. I even had enough extra leg length to cut a piece for the 2" coupler that joins the 2 parts of the hard 7 pipe. HoseTechniques emailed me back a while ago and said that their 2" elbow was actually out of production or something - that would have been a perfect option had I been able to get my hands on one.

I'll take measurements/pictures of the trimmed elbow next time I have it off. I'm so sick of taking the IC on and off for all the trimming that I'm just going to leave it on there until I have a better reason to take it off again (unless anyone could benefit from this information right now).

Question: I don't have an STi scoop/splitter/bellows yet, so should I just run my whole WRX set up, or would I be better off removing the smaller WRX rubber bellows so air can get to the whole intercooler (although not directly focused on it).
