I'm probably just an idiot, not being able to figure this one out, but what does that gold nipple connect to? (it's circled in torquoise and labeled "WTF?")
Boosting a B15 SE, btw.
BOV shown came from an Avenir.
This project has taken far too long, sadly , going on 2 months, school hasn't made it any easier to get stuff done.
Also, anyone know where I can get a 2.5in 3 bolt flange to fit the stock Avenir exhaust turndown for my DP?
