My Vin# gives me the info that the truck is an 2004... but the driver door sticker says 2005

Here is what i have under the hood:

Under the stock air box is a "Spectre" autozone filter for $29.00 and a rubber cap $3 from lowes to cap off the magical hole on the intake pipe i honed out the top inside of the airbox so the rubber cap would fit nicely.
I am debating which air intake system to buy between these 4 big company's.
K&N, AIRAID, VOLANT, cFe.
I have noticed the K&N 57 series (plastic tube kit) also removes the other plastic box "Resonator" that say's: VORTEC ( i have no idea what the box is for)? my guess is that if the black box that says vortec was removed and just a straight pipe with a air filter i could see more gain...+ loudness?
I would go with the 77 series but I do not like chrome & I don't think metal does a good job as far as heat resistance.
The other ones look nice like the Volant but I really like the LOUD rumble an aftermarket air intake makes when you punch the gas pedal:) and that my friend is why I am Deciding to go with K&N, but I want the professionals opinion which one is best.
note: MPG isn't an issue with me, the harder i drive the less mpg i get if i granny it my mpg is fine.
Please feel free to chime in.
