Could you get one of the 4" downpipe back systems, then have a 4" downpipe made by Smoke House Diesel? His look better than mine, that's for sure.
Texas Diesel Shop had a group buy earlier this year, but they had fitment problems with the downpipe and around the T-case.
You could also get some SS flex pipe, and install 2 more hangers- one right in front of and one behind the t-case on the cross member (or the nearest one). It may not LOOK the best, but the stainless flex holds up pretty well. Should last another 14 years.
