||If you don't have the AC compressor installed, you can do it in the car(underneath) without much issue. Maybe take the alternator off on the passenger side to access that side better.
You will have to shave a bit of the OEM engine mount on the driver side to fit the piping.
I installed the inlet piping to the turbos with the motor out, and did the other pipes with the bumper off. Just keep taking thing off until you can get access to it lol
