I'm fitting a full 2-1/2 inch exhaust system - out the rear - to my ERA. The mufflers and headers are out being ceramic coated right now but I hope to have them back and hung within 30 days or so. Do you have the standard ERA Jag rear suspension or the ERA suspension? ERA says you can't run tailpipes with the ERA suspension, although I suspect if it was custom fabricated to run up real high up and over the rear half shafts - it might fit. But - I can't be sure. It's possible that run up that high the tires may start to hit the pipes even if the suspension clears them. So, if you don't have the Jag suspension you may be stuck with the exhaust turning out in front of the rear wheels. I'm managing to fit 2-1/2 inch tail pipes by virtue of using the Jag rear suspension and only running a 255/60-15 inch tire in the rear. Even then it is tight.

If the quality of the exhaust sound is the main issue, I don't know how much difference tailpipes will make in the car's sound. I'm using Spintech mufflers which I understand are pretty loud. The usual means of mellowing out a car's full length exhaust system sound (besides muffler selection) is to run an "H" or "X" pipe connecting both sides (and increase power slightly also). It probably wouldn't be impossible to do so on a Cobra - but it would be a real challenge.
