ACE CS400 installed!!!
Paired with the HKS R-Spec front pipe, oem midpipe, and TRD High Response Muffler Ver. R.
I got it installed. Took me about 5 hours because I'm slow and it was probably the most difficult header to install. I tried to snake the overpipe portion in like I did with my AVO, but because of the merge collection, it would not budge. So I unbolted the engine and jacked it up. That was probably the most surprisingly easy thing to do! The bolts came undone with no problem at all, and lifting the motor 1/4 of an inch to slip the overpipe portion in was a breeze.
Now... the annoying part. The overpipe! That piece of shit is by far the most difficult part I've ever had to install. The three bolts had to screw in and were at funky angles. The 2 were pretty easy, but the top right bolt can kiss my whole ass. That sucker was so hard to thread and then tighten I almost gave up. I had to remove a portion of the plastic paneling in the wheel well to get my socket lined up. Then, the overpipe-to-front pipe part had threading too! I've never seen that before. Once again, that was also a nightmare to line up, thread, and torque.
I plan to do some data logging tonight and send it off to Zach at CSG and let him do his magic. I'll be curious to see how it stacks up against the HKS header it's replacing and the Nameless/Cosworth I had on both my FR-S and BRZ. If all goes well, I will be the last mod I do for a long, long time. Hopefully this weekend or next week I can get some sound clips of the set up.
