I think it depends on whose overpipe you buy. gmookher has the one from Perrin, which follows the bends of the stock overpipe. If you have an overpipe with the same bends as stock and is bigger diameter, it's basically the same size as the stock one with heat shields in place (on the outside anyway).
SRT straightened their overpipe out a bit to improve flow, so it's easier to maneuver. I found the SRT extremely easy to install, no engine jacking required. The downside, as we've seen is that as currently designed it doesn't clear auto transmissions. Some slight tweaking should cure that, without losing much, if any of the straightening.
I think Nameless were actually the first to straighten out the overpipe, and they made it considerably straighter.
