Wow this is an old topic, my exhaust has gone through several changes since that point. First I completely redid all the piping from the stock header all the way back is now 2.5 inch diameter, the glasspacks are pushed forward to about the stock precat locations, V-band clamps behind these with v-band clamps mounted by the rear axles as well so I can take a section of pipe out to work on things.
Here are a couple pictures right before the current setup, all 2.5 inch piping.
