[s-cars] Stromung, worth it?

[Scott Munger]

Side by side, the stock system has
	- 10 70+ degree bends not including what's inside the muffler and resonator
	- 14 other bends

The SS has
	- 3 70+ degree bends not including what's inside the muffler and resonator
	- 4 other bends

I'd agree a dual 2.5 system would flow better with all equal factors, but
there is some serious piping in the stock system.

Some good discussion is up here
	http://www.urs4.com/technical/engine/UrS4_exhaust.html

Hard data would be nice... but oh the sound is so nice.
