Is there an easy way to center an exhaust?

[gobble]

I have an Anytime exhaust and B&B headers. I noticed last night that it is so far left of center to have melted a tiny bit of the rear bumper. Is there an easy way to center this? I was thinking maybe loosen all the joints, hold the exhuast all the way to the right, and retighten.

In case anybody wonders for future reference, I was able to loosen the nuts on the exhaust and the cats, zip tie blocks of wood around the exhaust tips to center them and retighten the nuts and now have a perfectly centered exhaust.
