Re-hung my 3"

I had it hung low due to the original cross brace under the drive line, but it ended up dragging on a high curb driveway.  I just took the brace out and tucked it up higher and cut off that ~2" end of the adjustable hangar in the picture.  Any thoughts or tips?

I got rid of that brace a long time ago.

Looks like the main problem is that it's low up front. You could go up at least another inch and tuck it up tighter to the transmission X-member.Then you could make the whole thing tighter to the floorpan all the way back to the muffler, and bring it up too.

Wow, thanks for the quick reply.

Ok I will keep that in mind for when I decide to adjust it again.  I was also considering adding a hangar from the original holes in the transmission mount that held the original cat converter.  With my tools and expertise I had a hard time tightening the down pipe, so I left it where it was for this re-attempt.

Adding the additional hanger might not be much help if the downpipe is a touch long and just hangs lower. However, if the exhaust is just being held up by the downpipe flange bolts and the muffler hanger, you probably should add one for extra support.

You might be able to loosen the downpipe and separate the rest of the exhaust from the downpipe. Then put the DP where you want it to be (raise end up, etc) and support/secure it in place while you tighten the DP back down at the turbo. If you don't have an extra set of hands, use something as a spacer between the DP and the x-member and hold it in place with a bungy cord or something. Just an idea.
The end of the DP looks slightly angled down in the second pic, so some adjustment may be needed to get things higher.

The more I stare at the pictures the more I see what you are saying, I think this was a result of having that cross brace in there when I aligned and tightened the down pipe.  I think it must be angled down a touch more than it could be.  Thanks.

I think I could rig up another support while I'm at it pretty easily too:

It's Gumby's fault.
