Wow. That is a scary question.
In a limited travel suspension, a panhard can work... but still has its limitations going into bind outside that window. A j-bar can work as well... but at the sacrifice of OE muffler placement. And lastly, a watts can work with all of what you questioned. Packaging of a 3" system with say... the Lat-D 3 link is a definately possibility.
Then again... there is always mandrel bend oval exhaust tubing.
