Finally got my FI Long Tube Headers installed. Now I really need to get an UpRev-based dyno tune on this car soon. Only driven ~1hr and mostly in traffic since, but so far everything seems peachy.
I chickened out on doing it myself for once, Baker did the headers install (and also swapped out my 7AT fluid while the car was in there).
Many thanks to Jason and Paul @ Baker Tuning for handling this install. This was the first time I've entrusted my car to an outside mechanic for a parts install, and they did an awesome job and were a pleasure to work with. Highly recommend them
