we can agree to disagree, maybe i'm mistaken, please proceed with thread..
great vid good runs.
The consensus on this platform is as long as you have intake, downpipes, intercooler, tune, you are "FBO", as the cat back doesn't do much on this car.
Technically, you can bolt on a upgraded turbo or single turbo too, so the full bolt on is a loose terminology throughout many platforms.
