What exhaust are you guys running?

[Kixwy2]

My exhaust "system" is seriously ghetto. Some PO added a dual exhaust with square tips that sounds like an old guy farting. Plus it's rusty and has a few holes, and the gasket from the headers is shot.

I have this great new motor but I can't hear it!! So I need some ideas for an exhaust, and also how easy/difficult they are to self install - or get it done somewhere. I'm looking for a nice, throaty sound like you'd find on the original trucks, but not super loud. I'd actually kind of like it to be a sleeper and shock 'em off the block, so to speak.

I'd love to hear and see what you guys have done and approximate cost, so I can start saving my pennies.
