I just installed my AFE mega-cannon. Mr. Bobs distributing supplied me, great service at a pretty good price from what i could find. Anyway, that air filter is LOUD. Not for the faint of heart. I didn't really know what to expect, but all i have to say is my wife is not going to be happy on our next trip. Hey its my truck I'll do what i want right, well she funds the mods so i guess she might have a little say. I will admit it does sound pretty damn cool though, you definitly will get a closer relationship with your turbo.
