This DIY is a permanent (under normal conditions) replacement for the stock E36 rear exhaust hangers. It really couldn’t be simpler.
For a car that isn’t driven on the track, this fix shouldn’t be necessary. But for those of us who do track our cars and suffer the indignation of at-least annual replacement of the hangers, this is the fix for you.
When completed, your exhaust will be aligned exactly as it would be with the OEM hanger, except that it will not move unless you beat on it, which I have demonstrated and documented with photos.
Materials I got from Home Depot:
Step 1
Jack the car up from the rear high enough to get under it and remove the rubber doughnuts from the center exhaust support. Of course, support the car with jack stands before proceeding to work on it.
Step 2
Support the muffler with a floor jack.
Step 3
Remove from the muffler the metal holder and bracket and lower the muffler enough to get to the tops of the hangers (where they attach to the car). Remove the hangers.
Step 4
Cut two pieces of the angle bar, each seven segments long. Install the metal holders by inserting the bolt through the center holes of the angle bar oriented as shown in the picture. The bolt is only threaded toward the end, so you need to use something for a standoff. I cut in half the piece that was part of the original hanger, even though the only good picture I took shows it full length. All you have to do is cut through the plastic sheath and it will come in two (shown in the blurry pictures of the installed hangers.)
As an option, I could have used the plumbing piece shown as a standoff.
Step 5
Reassemble, placing the angle bars oriented as shown in the picture.
Below are pictures of what it looked like after I damaged it when I drove off a curb getting out of a weird parking lot. The curb hit the underside of the muffler and pushed it up (the muffler was undamaged except for some scratches). The nice thing to know here is that the angler bar crumpled and bent to the side in a way that relieved stress at the attachment points. There was zero damage to the car. I was at the track when I noticed it, and all it took was a hammer to straighten out the angle bar to get back in business.
