Your favorite mufflers for your Magnum?
I have Classic Chambered PowerSticks on my Duster now but those are on the loud side and have a very raspy, open sound... I'm young so my go-to "quiet" muffler is the Dynomax UltraFlo, I think the Super Turbos are too quiet lol. My cousin's 440 '72 Polara had UltraFlos and they were perfect, I also ran them on my old 1988 Fifth Avenue with a 318 and have one on the Jeep in my sig. All drivers with lots of street use and none of them had any drone. They're also good quality, the muffler on my Jeep is about 3-4 years old (lots of winter driving and we have a form of road salt here) and it only has slight surface rust along the welds.
