2013 ls3 help with bolt-ons
Headers and CAI are the easiest and most affordable bolt on. I recommend either Kooks headers or American Racing headers.
Also for a CAI we like to use Roto Fab, and Cold Air Inductions.
Just about every 6 speed 5th gen with these two mods lay down around 420 rwhp on our dyno.

I think everyone hit the nail on the head. The CAI & full exhaust is typically the basics. The LS3 guys love the 3.91 gears from the 1LE too. For CAI you will want either CAI Inc, Roto-Fab, I've had experience with both and you can't go wrong with either one.

LT headers, CAI, Ported TB.... the TB wont give you more HP but will make it more responsive...go CAT-less if you can or high flow cats, UD pulley...Dont forget the tune!
