Hey there people....I've got my K&N CAI up for bid on ebay, practically new, no reserve...I just switched it back to stock. I loved it, but I don't know which was louder...the intake at WOT or my wife screaming in my ear about it....yeah, yeah..I know "who wears the pants" type thinking now, but this is the main road trip vehicle we have...if I were flying solo I'd keep it for sure. I still hope to sneak a "civil" catback in, should be less cabin noise with the length of the mega cab....the intake roared pretty good through the firewall. It's in the classifieds too if you all want to take a look. Thanks guys.
