Would like my fellow Dak owners for their opinions and suggestions on an exhaust setup! I'm not interested in the loudest sounding exhaust, but more interested in possible? performance gains.

I've heard good things about a SI/SO full 3" setup. AT3030 muffler was one that was recommended that sounded good, and performed good.

Dynomax super turbo's/ ultra flow (too much flow?) are also recommended as well, but not sure if it's more specific to the 3.9Ls.

Magnaflow was another that was suggested

Do people prefer a full 3" SI/SO setup or SI/DO setup with 2-2.5" tailpipes?
