April 2023 Update:
The exhaust leak ended up being between the headers and the mid pipe. I've attached a photo where you can see the gasket material blew out. I also replaced my front wheel bearings preventatively as a rushed diagnosis led me to believe the left one was failing. Turns out the play I was feeling is likely the spherical bearing in my TCKline camber plate.
On that note, I need to call them to see if I'm doing something wrong. With the small strut tower openings, I'm only able to get -2.8 degrees of front camber. It seems as though Ground Control and Vorschlag users are able to achieve -3.5 no problem. Hopefully I'm doing something stupid and it's inherent to the design.
The brake upgrade continues to be an excellent investment. I now have 600+ track miles and ~700 street miles on the front DTC-60s, and they still have a fair amount of life left. Even without coding and changing the rear calipers, I'm seeing a slightly reduced braking distance. This may be because of how soft my suspension setup currently is, but I'm thrilled.
As I continue to get comfortable with this N54 intake, I'm noticing oil consumption is drastically increased at the top of my rev range. Driving 250 miles on track this weekend used almost 2 quarts. Top speed on VIR's back straight maxed out at 133.2, I'm blown away by the difference the intake and header combo makes on track.
On that note I PR'd again hitting a 2:18:00, improving by 2.2s thanks to some incredible coaching with the Tarheel BMW CCA. I've driven with several orgs now, and they are far and away the best instructor group I've experienced.
