at this thread.

Not to throw too much commentary, but Starbucks plus half a bottle of Jack, or like 10 Stacbuck's Vente with triple shots of espresso.

No magic suction fans or turbines are going to "suck" more exhaust out of the car. Forget about it.

If you want to improve flow, run Euro headers (no cats in the headers). The ESS kit is supposed to be run that way anyway, but Roffle and Beedub are the experts on that.

With the right ESS tune, I supposed you could run totally catless, but the car needs to be tuned for that, otherwise, well, the word "boom" comes to mind (too lean a mixture).

Might as well run full catless anyway, since you're no longer emissions compliant in CA, and will either need a "special" inspection or need to make the car offroad only, or put it back to stock prior to having it an inspection. (Car will not pass visual inspection, heck, even an intake that isn't stock and doesn't have a CARB--California Air Resource Board--sticker, or even a air filter w/o the carbon, will result in a fail.)
