Dynomax Race Bullet. Loud and deep. You'll be able to hear it all the time.

Here's a quick vid I made.

That sounds good however I think the OP is wanting a little different setup.

The flow master exhausts are cheaper than the manganous because they are made with cheaper materials. I'm getting a manga flow exhaust for my 04 f150 fx4 because it has a deeper tone but can't really hear it from the cab. Also I saw that you wanted a k&n 77 series. There's just one thing about those, they come with steel piping instead of plastic and for a cai it's better to get the 57 series because it has the plastic tubing which doesn't trap a lot of heat from the engine where as the steel piping is trapping warm air. Hope i helped

true dualed magnapacks and high flows are pretty loud. Also Banks Monster si/do kit with high flows is alot deeper but not quite as crackly.
