Long tubes are more expensive but have proven to make more power. Z1 makes a great long tube setup with color/options. Also is cheaper ($500) and easier to install than the Stillen G3s.

If you are set on short tubes, I would consider the AEM setup for $380. Aesthetically it looks great and comes with heat shields to make heat soak(power loss) less of an issue.
