WOW...Just poking around and it seems I get mentioned on boards I don't visit. Well I'm registered now and will be posting often.
My current LTD LX is still a roller right now, but I've had 4 of them with several different combos over the last 15-16 years, yeah I'm old. I do plan on using a built 347 shortblock, Brodix heads and a 3500 stalled AOD.
The LTD should be running by now, but I spent the last of my budget on my newly purchased '85 GT. BTW...Black, loaded with options, T-Tops, very little rust, T5Z, 5 lugs and lots of suspension mods.

Way back in '91 on my '85 SSP LTD (I had a 308 in it), I used stock '86-93 headers, stock '86-93 four cat h-pipe, and a 2 1/2" Dynomax SuperTurbo exhaust kit for an '87-93 GT ( IMO...cheapest one out there with good mufflers). I added the '86-93 Mustang H-pipe hanger when I swap the single hump crossmemebr for a double hump crossmember out of an '84 5.0L AOD cougar and the '86-93 Mustang tailpipe hanger on the passenger side. The stock LTD LX hanger will work on the driverside. I also used the stock gas tank. I added 2 1/2" pipes on the other 3 LTD,'s that I've owned in the past and never swapped the gas tank in any of them.
The '86-93 Mustnag GT Dynomax kit comes in 3 sections, flowtubes, mufflers and tailpipes.
Go ahead and yank the old exhaust.
Now go ahead and install the crossmember, and the two hangers. Next install the headers and h-pipe.
Go out back, install the tailpipes and just hang the mufflers on. Next , bolt on the flowtubes and measure the gap in between the flowtube and muffle. Use some generic 2 1/2" exhaust pipes to lengthen the pipes about 5 inches. Get some pipe about 12" long that will slip over the flowtube and slip into the muffler. These 2 1/2" extensions are common and should be about $5 each.
Once you get everything hung, go back and make sure everything is even and has clearance. Then tight/clamp/weld your new duals together.
The '87-93 GTs have a turndown at the end of the exhaust. Even though they are a little short, they still look OK.
