I have an Dynomax Ultraflo welded on my TA. If you are looking for loud go somewhere else. When I got the TA it had a Midas replacement muffler. At idle the sound level is about the same but the ultraflo has a much deeper tone. There was a noticeable gain in performance. And most important it is not loud at highway speed.

What size ultraflo are you using ? I want something quieter than the flowmaster.I was thinking 3in offset in and 3in offset or center out. The offset out should be a little less loud than the center out.
