Anyone have any experience with Paradox Mufflers?

Best Sounding Muffler For V8 Truck, Car, 4 cylinders, V6, and More

The best sounding muffler for V8 V6, 4 cylinders and more. Deep sound and no exhaust drone.

Their no-drone technology definitely has me intrigued. I'm looking to upgrade stock exhaust on my 2013 5.3, but will run far away from anything that has the least threat of causing drone. I had a single Magnaflow and resonator delete on my '09 5.3 - had great sound, but droned at 1800-2300 rpm with medium load, such as going up a slight hill. Drove me crazy, and I found myself kicking it down a gear even when not needed, just to make that sound stop. Exhaust shop added in a quality glass-pack behind the MF which helped, but did not eliminate the drone.

I have a feeling I'm going to be purchasing one of these soon. My big questions are cat-back duals vs. staying single, and, if staying single, to delete or not delete the resonator.

Looks loud. Here's a soundclip with a 2011 5.3 in a Silverado and silly twice-pipes.

I got flow fx muffler and resonator delete and have no drone at all. Could've been the way your exhaust shop welded and positioned it? No clue
