I started unbolting most of the factory heat shields that were on the factory J-pipe, to make room for a socket wrench later. I also, carefully removed the two sensors from the factory pipe, to later be used on the new TXS 3" j-pipe.

I was lucky enough to not have any issues with unbolting my stock J-pipe. I hit them with PB blaster the night before, and through out the day of the install, then with a blow torch right before torquing them off with a 6 sided socket wrench and a whole mess of extensions.

I ended up cutting a little part of the top heat shield to make it a little easier when fitting it back on with the new pipe, although it's probably not needed.

I test fit the pipe onto the turbo with the new supplied gasket and everything fit together perfectly. I ended up not using the upper bracket as it was not needed, and only used the top heat shield that is near the belt.

Screw in the factory sensors and made sure the plugs went back to their original spots, as you cannot accidentally switch them. They physically won't fit.

Finished installing the upper heat shield and torqued down all the turbo studs. I'd recommend using the Grimmspeed machined studs, if you happened to chew up the turbo stud threads or nuts, which is pretty common.
I had to use 3 or so socket extensions going from the turbo studs to the front of my drivers side wheel in order to get the top rear nut tightened properly. Definitely use a 6 sided socket when doing this, I tried a 12 point, and that didn't work at all. But the back portion of the J-pipe bolted up just fine, and mated perfectly to my Namless Performance Axleback.

With the J-pipe installed with muffler deletes, this thing is mean and LOUD. I later had 5" Magnaflow mufflers installed on my axle back to quiet it down a bit.
