I needed to check the downpipe/catalytic converter for any leaks. I took the effort to remove the downpipe from my car for a complete inspection. It was a good bit of work and creative thinking that was needed to get the completely out. The video shows where the bolts are. I wish I would have had the energy to continue videotaping the whole project, but I didn’t. My brother was doing all the work and I am recovering from an previous auto wreck. Anyway, when taking the exhaust out just get creative with wiggling the pipe until it works its own way out from between the frame, axle, and harmonic balancer/crank pulley. Come to find out, the exhaust gasket was no longer any good.
