if using stock turbos there is no need to get anything but stock. In a previous build I thought the same thing and got SS lines just for the hell of it. The SS lines that I've seen do not come with the restrictors such as the oem banjo bolt on the passenger side and the junction on the drivers side. I was told that the ball bearing turbos needed restrictions and thrust bearings were fine without it as they needed more oil. This was before I knew what I do now and the car come stock with restricted oil to our oem thrust bearing turbos. With my current build and new oem CHRA's I went with the stock lines. Be sure the banjo bolt with the K stamped on it is installed on the RH side
