My first set of clamps at that mid muffler joint leaked as well. It was through a mistake of my own in trying to tighten the clamps before the pipes were level with each other. I didn't bother to level both sides to each other so that the clamp can smoothly and evenly squeeze and form to both pipes. The weight of the pipes on each other will cause them to sag and create a slight V if that makes sense and pushing up on both sides so that they tuck up closer to the car and make a smooth transition from one pipe to the next.
Napa sells the clamps at about 8-10 bucks each so I bought two more and the orange high temp gasket sealer. I used a floor jack to level the pipes the second time and that combined with the sealer, I have zero leaks at all.
I emailed Steve in detail about this to hopefully include this in their instructions so that more people don't run into this leak issue, but that may not have happened yet. Best of luck to you.
