Got mine in yesterday, more pictures here. It is true a stock 02-05 y-pipe would be very hard to make work since the elbow points are ~1" further apart. I was already using a moded Samco 02-05 y-pipe so it wasnt to tough to make work. With the passenger side connected to align with the compressor outlet i cut the drivers side of the y leaving ~1" of hose hanging past the elbow. I then got a 2" od exhaust pipe to sleeve in between the hose and give me the ~1.25" extension needed. Only other issues were moving the cruise control actuator a bit and some adjustment on the condenser tank position.
Runs much smoother without that big piece of aluminum banging on the firewall. I dont have it mounted at all right now. The hoses are able to hold it in position with no problems. Well worth the effort for anyone thinking of doing it
