If you are wanting to just be loud go with Flowmaster Super 40 or 44 dumped. I've run both before and they do sound good. If you want performance and good tone start with a Magnaflow y-pipe to a 14" Magnaflow dumped. And if you still want to be obnoxious (like me!) add an e-cutout behind the y-pipe. I never go with "kit" exhaust systems. I just let the exhaust shop use their own piping.

This is a different e-cutout in this pic. It was a butterfly type with a dump from ebay. it failed extremely quick, so I replaced it with a e-cutout from Doug's Headers.
Here's the new e-cutout.
