Sorry it took so long to get back to you. After the 1st of the year my whole life went down the ****ter.
Anyway, the Cold Air Intake is a really nice piece and is 50 state legal. The exhaust is really good too and if the cops try telling you it's not stock have them crawl under so they can see GM stamped all over it. It could be a little louder but it still gives a nice tone.
I noticed in you signature that you have the GM Performance CAI and the GMPP exhaust. What do you think of your intake. I was looking at getting one for my 2010. Also, I'm interested if you think the exhaust is worth the money.
