I also had a muffler delete and it droned like crazy. So what I did is weld on the stock exhaust flap onto the end of the exhaust. Then I can control it through JB4 Flap Module. When the flap is closed, there is nearly no drone. When it opens, car makes all the noises in the world! I'll try to post a video later.
