I think the stock pipe comes back a good bit farther than the new dp. Also the stock dp is going to be a good bit smaller than the new fbd exhaust

I would say no, the stock dp is easier to get out than trying to mate the 3.5" factory pipe to the 4" FBD. The stock exhaust has a flange where the FBD is all slip jointed, and they downpipes are not the same length. One hack of the stock pipe at the first bend under the truck and the whole thing will drop right out. Then the FBD pipe slides up in there without too much trouble.

i would go through the trouble and support your tranny, and remove the crossmember and pull the stock DP in one piece if possible. i have had 2 DP's not fit right and had to weld the stock ones up to reinstall it till i got a DP that would fit right.

My bad I was thinking we were talking about 7.3s never touched a 6.0 sorry :dunno:

You should be able to unbolt the stock system at the cat flange and bolt the new FBD system right up to it.
