I have 2" wide SS banded clamps already. Those Princess Auto clamps are a nice price. Wish I knew about them earlier. I have been out to Princess Auto a number of times and have never seen them. I may give them a try because I think my 2 " wide clamps are deforming a bit and relaxing.

I found a short stub adapter. 2" ID / 2 1/8 OD. Fits perfectly over the header tailpiece and in to front pipe of the Simons exhaust. I slotted the adapter where it fits over the 2 " tailpiece to ensure that I get a good connection.

After the repair, the noise was gone. However, after driving around for several days and looking for bumps to try and shake things up, the noise is back; but reduced. A little poking around showed that the rubber strap on the flex hanger at the bracket at the front of the transmission had failed. I have to come up with a better mount for that location. It also looks like my 2" wide SS banded clamps from Canadian Tire have deformed and are releasing some of the clamping force. The Princess Auto clamps may be the answer.
