In addition to the muffler expansion tool, I bought a few pieces of exhaust pipe reducer sections (short pieces about 6" long that go from 2.5" to 2.25", and 2.25" to 2.0" - most any auto parts store carries them). I used these pieces for trial fit (much easier and less risky than holding the pipes up to your car), and, they can be used to slightly "shrink" the opening if you go too far opening a pipe up. You can tap these onto the end of the pipe (either side, header or exhaust pipe) using a block of wood and rubber mallet to fine-tune the adjustments you made with the expander tool.

Once they fit snugly, a little hi-temp orange silicone will make it leak-proof.
