UPDATE: After toying around with the new setup, I would like to add some comments:

1) There is a vibration issue at higher speeds and specifically when upshifting and keeping the car in 5th gear. I drove the car and went from 80 to 210 km/h (5th - 6th gear). I do not know for certain if the vibration comes from the bottom shield contacting the headers. Might have to do with wind gust on the downplates, m or the new tune, maybe. But then it should do the same when in 6th gear. Or prehaps at higher speeds it stabilizes somehow. Do not know. I will see if there is anything loose and adjust. I did a recent Whiteline positive traction kit install, so that might come into play. Though the nosie came from the engine bay.

2) I went back to OFT Stage 1 93 octane tune. The car did not feel right with the custom tune shiv sent me. Though it was a 91 octane one. I did not dynoed the car, it might gain some ponies with the custom tune, but numbers that I can not feel are meaningless to me. With Stg 1 93 + headers the car has more "oomph" and feels more stable.

3) It takes some time before the exhaust starts giving rich rumbly notes once you srtarted it. Cold weather makes the exhaust sound better

That's all. Just wanted to share my thoughts.
