No noise regs, lighter, and freer flowing with less effort.
Nothing different today in racing, providing you can make it quiet enough for regs.
Most road systems are rear exit as they're off the shelf items rather than custom jobs. And most dont dare to be different anyhow.
And to get decent ground clearance with a side exit most cars need the sills etc notched a little.
