Next, the pipe was cut with a saw, right in front of the last hanger. This let us get the pipes out later without removing shocks and stuff. A soap and water solution was mixed in a bottle and sprayed on all the hangers and rubber isolators. The soapy solution let the hangers slide out of the isolators a lot easier. But, if you don't believe us, try it dry. All of the hangers were popped free with a prybar and then the factory system was snaked out. Note: Be careful, because the factory stuff is pretty heavy.
