Suggestions for muscle car sound muffler without drone

Guys. Hands down the best muffler for muscle cars without drone is the Heartthrob HVS muffler. I have one on my 99 z28. These cars are known for drone in 6th gear. My car doesn't drone at all. Plus it has a great sound. It puts 420 hp to the ground. My duster will get pair of these when the time comes to put exhaust on it.
