BIG IS BETTER" hell go 4" your not going to see any loses in anything

and im still failing to see how if you think critically about how a turbo system works that you can say a smaller exhaust will improove respeonsiveness on a fi car??
Its on a ca18det, went slower down the quarter by changing to a 3", said he had more responsivness with the 2.5" and had more down low.

I have not really thought about it to be honest. just wondering what others think. Even the back pressure is important on a N/A, to some extent would it not still be the same for turbo?
