Your side-pipe slip-joint may need a little more than just some sealant. It probably would help if you massage the fitment of the pipes a little.

I used a tailpipe expander (about $12.00 at an auto parts store) and a couple short pieces of exhaust adapters (2" on one end, 2.25" on the other) to tailor the fit of my pipes. Using the soot pattern on your pipes as a guide, you can determine which pipes have the worst fit. Using the exhaust adapter piece with a small block of wood and a rubber mallet, you can pound the adapter onto your individual pipes to "resize" them slightly. You can tighten them slightly by forcing the adapter on one way, enlarge them slightly by forcing it on the other direction. For more extreme adjustments, use the tailpipe expander tool.

After massaging the individual fit, the copper RTV should be able to seal them up tight (they WILL be more difficult to R&R, though, as the interference fit gets tightened up).
