[QUOTE="01ssreda4, post: 5483, member: 477"] The only thing you are left with at this point is to reinstall, and you will mate your muffler exit to your tailpipe inlet which mine was approx 14 inches away from each other. I would recommend a mandrel bent 90 degree. If you make your cut very carefully, it will basically bolt the two together, no rear side welding needed. I designed my system with two clamps for ease of remove shall I ever decide to change mufflers. You can hard weld one end and only use one clamp if you wish or like stock and have no clamps. Its all up to the installer. You could also ditch the tailpipe and run a dump straight off the end if you wanted as well. Here is my final up bend that is replacing where the stock bend/Y merge was and my two clamps. Notice my adapter is on the upper pipe, and that's what my lap joint clamp is gripping.
