Exhaust hanger mod............a success.

Exhaust hanger mod............a success.
Excuse my sorry attempt at a write up, but I posted as many pics and instructions as I could. Any questions just let me know.
As some of you know, I was very unhappy with the way my exhaust tips hung and I had given up on hose clamp and zip-tie fixes. I knew that I had to come up with a long-term solution that allowed for some type of expansion and contraction (metal expands when hot). I came up with the following.
Here are some pics:
Nasty tip gap

I found it much easier to work with the B6 hangers because they are a lot more flexible than the B7. You can see the almost insignificant difference in the mounting hole placement.

Parts purchased at Lowes. The part at the far right was found in the hardware section where there are a bunch of different straight & angle brackets. Clevis pins allow for easy length setups. Not all exhausts are created equal and even the same exhaust systems have uneven tips. My left tip hangs about 3/8" lower than the right. I had to compensate for this as well.

This is where I drilled the holes for the clevis pins. The other holes you see was another setup I had tried before but didn't work out too well. I love it, they sit flush.

That little notch on each side keeps the zip tie from moving off to the sides.

I used two nuts on each screw on top of the threadlock.

Notice how the springs go OVER the clevis pins, you can set it up to run through the outside if you need more leverage. This however can be negative because it will create side tension to the point where it can come off to the side. Technically the rubber hanger is not used at all anymore, just the rubber hole part. I thought about cutting off the rubber "straps" but I left them in place for lateral stability and safety (in case it fails).

The rest is self explanatory.

You can see how much the springs have to give, there is a lot of tension here. The springs I used were tough and thick, I couldn't manually pull them apart for more than 3/8".
<img src="http://pictureposter.audiworld.com/49254/exh11.jpg">
As you can see, I'm very pleased with the results, and the best part, they still give! I imagine they will eventually hange a tiny bit lower after the springs have set in but if that's the case, I can zip tie together some coils or use a thicker gauge spring.

They didn't hang this perfect right off the bat. I had to play with the different settings of the clevis pin holes until they were perfect. It's impossible to set them installed. I found myself mounting, removing and resetting about three times before I was completely satisfied.
If someone want's something like this, I can put it together.

I thought of a million and one ways of doing this and I came to the conclusion
that there were more right ways than wrong ways of doing it. Just happens that this is the setup that I liked the most. It's clean and fully adaptable. Besides, I had to use parts that were available. Lowes only had like 3 different usable extension spring types.

damn dude, you really went to town on this one. I think i will just have the exhaust guy
heat and bend the bracket some more. I am not as creative as you on the weekends. :-)
