Just purchased a set for $65 locally. I'm painting them now with Rustoleum 2000 deg. paint so they stay looking good. Has anyone used these yet? Is there any difference between these and the ones from 05-09? I know they will fit...I just wondered if there was any difference in sound or performance.

On a side note I also picked up a Spectre Speed reusable drop in air filter to tide me over until I get my supercharger(it will come with its own intake). Has anyone used these before? They look just like the K&N filters. Any info would be appreciated. I wanted to get some opinions before I unbox. Thanks!
