Hello, this video picks up where the earlier video I produced left off. Also, here is the link for the muffler removal.    • How to Remove a Muffler and Tailpipe on a ...   During this video, I show you how to use the original factory muffler flange with the new MagnaFlow muffler. In order to make use of the flange, you will need access to a welder and a 2.25-inch inside diameter to 2.25-outside diameter exhaust adapter plus a straight section of 2.25-inch outside diameter exhaust pipe. Indeed, by watching the video, I hope I have answered all of your questions, but if not, feel free to drop your questions in the comments. Thank you for watching.
Here are the time stamps of key points in the video.
1. From 00:00 to 02:10, a hacksaw removes the triangular-shaped three bolt-hole exhaust flange from the original muffler.
2. From 02:11 to 04:07, an overview of the MagnaFlow 2001777 muffler is shown, and measurements are taken to use the original exhaust flange.
3. From 04:08 to 10:42, the exhaust flange and an exhaust adapter are ground, where they will be welded together.
4. From 10:43 to 19:36, the exhaust adapter using the original flange is welded into one usable exhaust pipe.
5. From 19:37 to 22:34, the weld seams are ground smooth using an angle grinder and a flapper disc.
6. From 22:36 to 25:01, an air needle scaler removes rust and the original exhaust gasket from the exhaust flange. Finally, a palm sander and 80-grit sandpaper complete the old gasket removal.
7. From 25:02 to 26:28, the air needle scaler and palm sander are used to remove the old exhaust gasket under the Blazer.
