I think the factory hangers are made of paper mache and they always seem to weather so poorly.

While pondering the problem, and looking for a quick fix, I came up with this approach.
It's just a piece of 1.5" (doesn't matter) square tubing with 4 holes in it.
Two are ~9mm holes on the front and read sides to bolt on the rubber hangers.
There is 10mm hole on the inboard side (about 1/2" lower than the 9mm holes)
There is M8x1.25 threaded hole outboard. This hole is in line with the 10mm hole.

I went with two donuts for this setup, three is doable by adding one below.

The installation trick - Get the donuts or springs on the muffler/pipes and put a long M8 fully threaded bolt through the trunk "saddlebags" and into the M8x1.25 threaded hole on the hanger. When you tighten the bolt, it draws the donuts/springs tight. No wrestling with fitting them under the car.

Hope this helps someone. I couldn't come up with a simpler fix! But I'll admidt that I blasted and painted it before install

The stocker uses three springs per side if I remember correctly... and you are replacing those with two rubber donuts?  Or are you hanging the assembly in a different way altogether?

I am only using two donuts per side. Stock uses three, and you can easily use this concept for a 3rd if you wish. My exhaust is pretty non-standard, but really now, mufflers and tubes are pretty generic. The only practical difference is my exhaust as pictured weighs 39 lbs lighter than stock. The donuts are really strong and will do the same work as the springs, but in my case, the donuts had an extra benefit with my "T" hangers.

You can modify this concept to suit, it's not intended as a concours replacement, just a serviceable fix that anyone can whip up in 5 minutes.

If you want to use springs instead of donuts, use welded eyebolts into the square tube (instead of bolts/donuts) and attach springs to the eye bolts.



These attach with a bolt from the inside of the rear trunk- the corners. You can use this to your advantage to draw the donuts/springs tight as the bolt is tightened. This means instead of fighting the springs to hook them, you can hook them when not under tension- and draw them tight with a wrench on the bolt.


Here was one I had previously made to use the "bolt tightens spring" concept. It worked well, but I wanted one a little quicker to make this time:



Here is the new one holding up the tailpipe section, using a "single tee" hanger. The singe tee holds the pipe up, doesn't do much for rotation.



Other hanger (slighly different) with a "double tee", holding up the muffler and cat. The double tee is welded in two places to the U-bend, so it prohibits twisting.



Iff'n you want to try this at home, feel free to modify to suit. It would be easy enough to add another hole on the bottom for a third donut or spring.
