Finally got these on. My car came with a 3 inch single exhaust when I bought it. I simply cut off the y merge, welded on the mufflers and new hangars and made an h pipe out of the 2 pipes going into the y pipe. As soon as I find some tips I will run it out the back. Here are pics showing the design and clearance.

The sound quality of that video isn't the best, but I can tell it's pretty damn loud. If I didn't know better after reading your SIG I would have thought it was cammed.
