Default Easy exhaust Hanger fix

So my rubber exhausts hangers have been breaking quite frequently lately (especially the passenger side one) so I decided to investigate and see how I could possibly fix the problem!

So I went out and purchased a new hanger (At 79 dollars a pop WAY OVER PRICED) and tried a few simple things!

I have a AA gen 6 exhaust and fitment is right on but I noticed a few things!

The all too fimiliar broken hanger!

After just 5 months of holding up that (in my experience light exhaust this is what it looked like)

So I decided to try to use a standard metal washer and sandwitch it in between the bracket on the exhaust and the grommet on the rubber hanger to try to ensure that the hanger is really at 90% so that there is no unessesary force on it! Also I thought that maybe when the car yaws and pitches on bumpy roads that that two mm's of washer would be just enough to keep the weight of the exhaust evenly distributed through the three hangers so that none will break! It seems too simple to be true but the shock absorbing diamonds in the hanger seem to be more relaxed when the grommet is in place! I will repost in a few weeks and see if I have the breaking problem again hopefully this will just be enough to do the trick!

I know this is quite a write up for a washer but it does seem to be a problem and an expensive one also!





You can clearly see the washer giving it just enough space!

Ive seen people take the mount and pour silicone into the empty spaces. It still moves, but the hanger doesn't break at its weak points.

this is what I did on mine, but I didn't use silicone, I used the brand dymonic, which is a little more harder than silicone when it is cured....lucky me, I have access to all of this caulking products at work....

you have any pictures of this? did you just fill the space in?

all of those exhaust hangers from the ones in the center section to the really uber gay ones on the muffler are just pure crap...

i am really starting to question the legitimacy of bmw's engineering.

I've seen this tip posted on the forum a while back and had tried it as well with one of my hangers. But the tip was to use the same silicone/ sealant used for sealing the windshield in place.

interesting post.. can you explain to me why you think the washer in between those two peices is going to help?

not trying to pick a fight but seriously just wondering...

i recently put a close to stock weight ss sport muffler back on my car and it seems that it moves around and wiggles all over the place.. and yes i am on my second set of hangers as well.
