Yeah there isn't much that can be done.
I spent about an hour with the local exhaust shop tying to figure an economical and legal way to do a better job.
For 180 bucks I got 2.25" mandrel bent piping from a new, larger flexpipe (from an Eclipse I think) back to a FlowMaster muffler.
The two bends were softened from 90 degrees to aout 80 degrees or so (thats an eyeball approximization).
