Hi everyone, I am new here and I have been lurking around the forum for information. I have a few questions. I have a stock 2008 chrysler 300c 5.7, 92,000 miles and I would like to add an air intake (AFE II or Air Hammer) first and then I have seen some places where changing the camshaft out will add horsepower, I'll put the link below. Does that really work and is it worth it? The next question is do I need to upgrade the exhaust? I don't really have an interest in upgrading it as it is expensive. Is there an order of upgrades that anyone would recommend or that you have done? My goal right now is to stay under $1,500.
