From the rear of the muffler back was a little less complicated. First, I slipped a straight tube into the rear of the muffler. Because the tip of the exhaust will exit just in front of the rear wheel I used a 90-degree bend at the end of the straight. In order to direct the bend in the proper direction I angled the end of the 90-degree bend slightly. I also welded a 6-inch extension to the trailing portion of the bend.
