As already discussed at length, an engine does not need any backpressure to "run properly".
I think part of the reason for this myth is people replace their highly-restrictive factory exhaust with a free-flowing one, and don't re-tune the engine to match the new VE characteristics. This can result in flat-spots due to incorrect fuel mixtures.
What this means in a nutshell is an engine will perform best with ZERO backpressure, if it has been tuned properly, and if it doesn't have weird cam timing as discussed by Jason.
Remember backpressure = exhaust gas left in the combustion chamber = not good for performance.
