There should be no reason to weld hangers on the frame, most of the custom stuff can use a steel/rubber type strap that is bolted to the frame(will require drilling holes). I dont have any pics of my exhuast at this time, but I have hangers to support the header collectors,& ahead & behind the muffs,& a set to support the tail pipes. I try to work off the frame crossmembers as far as mounting the hangers,& all are bolted. Just make sure you let the shop know what you want done, & they can show you several different hangers,& explain what they need to do to get the system in place..........AL
