| If your driving a duramax, I'd skip the intake. Many tests show the factory filter is far superior to the aftermarket ones. Dyno #'s show they also don't help until HP gets over 500 or so. I'm still running my stock muffler/exhaust, so there's some more money you can save, unless you like the sound that is.
