How's this for backpressure

I get the back pressure argument.

But really how much of a restriction does this 4.0L V6 need to achieve the right amount back pressure.

Any of you guys with exhaust system experience tell me how crushing a 2" exhaust pipe to half it's size improves performance or efficiency.

This is absolutely ridiculous just cut the pipe right before ur first muffler after the last cat and you’ll be fine I ran it like that for 4 months before I welded straight pipes to the back and had absolutely no issue.
