Removing DOWNPIPE from 7.3

This weekend I will be installing my 4" straight pipe. Can anyone tell me the best way to remove the downpipe? One of my buddies had a crazy time removing his and it seems to be a big problem. I've heard hacking it to pieces is fine but if anyone has the best personal experience and could explain, I would greatly appreciate it!

Your buddy must have an OBS truck... they come right out on these. One cut at the bottom and they come right out.

I put a 4" on my E99 last Sunday. A sawzall is your friend, as well as a impact wrench. Other than that it went on just fine and sounds great. have fun putting the new 4" down pipe in. That was not so easy. I did it with me under the truck and my buddy on the top. It took some PUSHING to get it up there but it will go. -Jason

Agree one cut near the bottom and you will have no issues once you get the bolt loose on the clamp on the top. Kind of difficult to get to. Then you will need two people for the new one. One down low and one putting the clamp on. Would be very hard with one person.

Getting it out is easy. Putting the new one in can be a trick - it does go up with minimal effort assuming you've got the puzzle piece in the right spot. I remember we wrestled it for a while before we found the sweet spot on my 01.
