Whats first? CAI, or Cat-Back?

Well in about 2 months or at least the first snowfall falls, my ride is gonna be garaged for the fall and winter months. Thats when i'm gonna start doing mods, but what to do first.

I keep hearing that 3rd TA have a very restrictive intake system, so i'm kinda leaning on getting that first.

The other is the obvious one most everyone uses first, which is a cat-back system.

I've looked at SLP for CAI, but to me it doesnt seem so much better than stock, cause it looks like it still uses an air box. I would think like a 9 inch cone, open, would be better. Maybe i'm wrong on that, but maybe u guys can help me on that.

As far as SLP cat-back, well it dont seem like that they make a dual exit one, they only have the one that exits on the driver side, which i dont like. But i know there alot of different Cat-backs, so i dont want to concern to much on that. So far i like Hooker.

A cat-back will be more beneficial than CAI. Not to mention you can make your own CAI for about $10 or so.
I like the Hooker cat-back.

A cone filter in the stock location is like the open element vs dual snorkle in the carb world, more hot air or less cool air. The SLP tries to do both by using a bigger filter and trying to pull the coolest air from the front of the car, however it carries SLP's heavy price tag so it is a toss up.
