to trim the ends of the hoses he sent with the pipe because they are a little long. But no biggy, also the hoses should have been sized a bit larger on the pipe side as they needed to be helped with a little lube to slide over the ends of the pipe. I thought about cutting the ends off the oem hose and using them but I didn't want to destroy that hose in the event I had problems with the pipe. So now that it's in and everything is fine the next time I need to get in there for something I'm going to use the oem hose by cutting the ends off it and replacing the 2 hoses he sent with the pipe. Not that there's anything wrong with them but I dont know the quality of the hoses he included so I would prefer to use the oem hose for piece of mind. Other than that the pipe arrived super quick, packed well, and the quality is good, I'm sure as good as what stillen sells.
