I am trying to install the corksport s pipe onto the msp turbo(t25). Anyways it is off the car. I cannot get a tool to get that middle bottom nut on, its at the apex of the first bend on pipe coming out of turbo. Its a 12mm nut and I cannot get a wrench on the nut for s***. Its only on a few threads but theres no room like for a wrench. What have you guys used to install, is there a special type of wrench needed that is bent a certain way??
