You probably get about 3 inches if I remember correctly. I'm not certain though.

What I remember is that he took off a clamp that had 2 bolts and he removed another 2 bolts from the left side of the catalytic converter only. It took him a little over 10 miutes in total to have the B2 Piston removed.

Here are some pics that are somewhat clear. I'm real sorry about the quality. This is why I didn't post them. I hope this helps you:
