That's what I'm building so I'm biased(Check my avatar). I have a few pics of the undercar set ups on some Cobras if you need ideas. The sidepipes exit by your ears and the noise is an issue for many. Especially on longer rides. I don't believe you will have room to fit a 3" exhaust anywhere under a Cobra. Toughest part is already mentioned wiggling it round the rear end, check the ERA site they have a few pics also showing a street car with side exits in front of the rear wheel. I vote yeah obviously!
