I just installed the aluminum VRSF outlets. They fit fine. Access is a nightmare but that is vendor-neutral even with the subframe removed. I would recommend removing the metal water pipe to make life much easier so you'll probably want the special rounded rectangular o-ring.

If we are talking about this

I installed mine in about 90 minutes from the top.

It's a little tricky getting both pipes to match up before installing the silicone connector, but that's how I did it. I tried putting the silicone connector on one end and then matching the other end. No dice.

I would also wrap the silicone connector in DEI gold tape. It's really close to the exhaust manifold. The adapter never gets hotter than 250, with the DEI gold tape on it when I check it with a laser temp gauge. So, the tape is worth it's weight in gold.

Keep in mind Silicone is only rated for 500 degrees at best. The exhaust manifold can reach that temp after a long drive, on a hot summer day, no problem.

Yes I did reuse the little v-bands. VRSF didnt provide new ones. They seemed fine but as you may know the 'hinge' is just flexible metal so if they arent virgin it might be worth ordering new ones. My Mitsubishi rattlers look untouched and I didnt have any issues.

Another recommendation I would make is to start with the back turbo and work your way forward. I had installed the 7.5" VRSF intercooler a few weeks ago and had to remove it to get the outlets lined up. The silicone coupler VRSF provides to connect the outlets to the intercooler (part of the intercooler kit) is very long and goes way up both the turbo outlet and the intercooler inlet.
