The midpipe is now installed.
I cleaned the weldings using pickling paste (nitric acid) and a scotchbrite:

AFTER:
Here is a comparison between the stock midpipe and the Trackforged one:
The pipe is passing close everywhere, but it doesn't touch!
I went for a ride and I have to say that I feel a little more power, especially at low RPM. The sound is rich and deep. It sounds more massive at idle.
My car is now having a burnt smell. I guess that driving it in the next days will help to get the pipe hot and stop smelling.
Thanks to Terracar and sentraman for starting this groupbuy and thanks to Trackforged to make a 3'' midpipe that is easy to install and doesn't hit anywhere.
