From what I have heard you will run out of curse words installing a 4" down pipe.

my diamond eye sucks it has about an 16th of an inch of space, and it rubs every now and then.

It took me a day to get just the down pipe in there and connected to the turbo. Pain in the a$$. I started at 4pm, ripped old exhaust off in no time. Then me and a buddy started working the down pipe. Quit little after 9 totally ticked off still not up there. Started early the next morning about 9 by my self trying every which way to get it up there. Quit and went to lunch and cooled down came back and was spinning it back and forth then all of the sudden it slid right up just as I was convinced it didn't fit. Finished entire exhaust by dinner. The main problem was the turbo flange hitting the flex joint on the up pipe, now that i have a solid up pipe that came with my egr delete I bet it would slide right up there no problems.
