3'' Stainless exhaust build ......tips or tricks help needed

[6600DURAMAX]

Looking / Working on first exhaust build for the K5 - going with 3'' stainless with an X pipe and Borla ATAK mufflers

FYI - for those with LS swaps and want full length headers - Speed Engineering headers will fit with minor trimming ...

Questions that I have -
1. any suggestions for mounts ? the exhaust seems to be around the same plane as the frame so hard to "hang" the exhaust

2. currently only have a stick welder so being really careful as I tack up using some 308L rods - any tips on this ( other than get another welder...)
