2014 Flowmaster Exhaust

I have only had my truck for two weeks but it's way, way too quiet. They really made the new trucks silent. Was looking at catbacks which start around $500, so I went to my local Muffler Man and had them install a Flowmaster super 40 3" single outlet. They removed my stock exhaust so I can put it back on later if I want, and made this up for me. Cost $270 and took them a little over an hour.

I've never been a huge Flowmaster fan, but I have ran them on a few cars. It definitely has the classic Flowmaster sound. There's a little 'helicopter' noise at low speed driving (25-35mph or so) but other than that it sounds good. It's still missing something, which I think adding a cold air intake will fix. I might look into replacing the Flowmaster with a Dynomax Super Turbo or Ultraflo later on.
