It would help more if it was at the turbo, pressure differential is king!

Btw, my flange was a T-6

I have the same setup minus the cut out. I got my duramax exhaust from a muffler shop for about $100 installed.

Mine was pretty basic. 3.5" downpipe into 4" with a couple curves to clear the crossmembers into a 4" magnaflow with turndown. 4" is pretty tight.

My DP expands to 4" at the bottom

How does that sound dumped at the axle vs all the way back?

I am not sure I just had it dumped. I dont really like the magnaflow thats why I am changing it to 3.5" so I could go over the axle.
