To remove stock from down pipe back and instal new 4 in (down pipe back) is it all just bolt on or is there any cutting involved. Truck is an 08 f-250 6.4. Thanks for the help.

Should all just be bolt on. Just undo the 2 bolts that hole the exhaust system to the downpipe and then undo the tailpipe section. Separate the pieces and pull them out. The dpf section will be heavy so an extra set of hands or 2 would be recommended. Also you will probably have to jack the rear of the truck up off the ground so you can maneuver the tailpipe section out.

Most likely the slip joints will be hard to separate. Get a big enough hammer and some PB blaster or similar product. A friend or two is very helpful too. Also un-bolt the hangers from the frame and separate them from the rubber isolators after you have it out from under the truck.

If you cut the downpipe it does make it a lot easier

Not if you don't intend to replace it

when you loosen the joint just in front of the muffler, kick the muffler towards the back of the truck and it will break free. Jack the back end up and that section will come right out. Don't forget to un-plug the four sensors from the DPF forward prior to unbolting the exhaust.

I just did this on Saturday... downpipe back, 4"- took me all of an hour and a half to complete it, and that was with a lotta running of the mouth with passing neighbors and taking a few minutes to watch one particular running lady pass several times..

it's almost as if Ford anticipated folks tuning these things...

I didn't have to jack up the rear, move a shock, drop the spare, or cut the exhaust- the tail pipe section from and including the muffler drop right out the FRONT of the axle.. I had to pull it toward the front instead of pulling it through the back..

the toughest part was separating the mid pipe between the DPF and the muffler.. I hit it with a rubber mallet until it was frightened of me, and it all but about jumped out..

The entire job would have gone even quicker had I had enough sense to NOT connect the tail pipe to the mid pipe before installing the mid.. that made it a little cumbersome to wrestle, but that is the only hang-up I encountered.

If you're doing it alone, you may want to use a ratchet strap to pull the exhaust together and ensure the joints are nice and tight so you won't leak.
