Everyone can have their own opinion, and this subject is up for debate but I don't know if I would go as far as to say it is "untrue". Yes forced induction cars don't need back pressure the way NA cars do but I have personally felt the diffrence. I had a car with 2.5 and when I put 3" I felt a diffrence in the butt dyno. So my experiences come from actually running the two sizes on the same car and I'm not the only one to ever report feeling a diffrence in the two. To each their own, many people go with the 3" and most of those people claim they will be going big turbo one day
Why do people try and substitute heavily biased anecdotal evidence or their "butt dyno" for scientific rigor?
science: it's for real.
I love my eurojet 3in tb but from what I hear they have slowed down production of it but I got mine from ese tuning back in jan i would hit them up if you want one. My friend had a 42dd on his gli it was louder than my ej and his would blow out fire balls some times. Here is a video of the ej 3in tb here.

I also read that turbos don't really need the backpressure like N/As do. but since we're looking at keeping it as close to stock as possible, i think the 2.5 is sufficent.
