Be wary of some of the aftermarket pipes though. When I was changing various hoses on mine I thought i'd change the coolant pipe along with everything else. I bought one off the link above from Tierod back a few months ago and another from GSF. In both cases I couldn't get them to fit properly. The angles were very slightly off, and the outlet to the oil cooler was located slighlty more to the right on the new pipe and was in the way off the oil filter once installed. I was lucky and my original pipe only had some surface rust so I derusted, sanded and painted it, but if your buying a pipe keep in mind you may need to mod or bend it slighlty. This happened with both pipes, don't know if I was just unlucky or if they are very slighlty off.
