True. Like Max mentioned, a video that I watched also talked about the better insulation in the newer models. So maybe I can go louder without a drone lol.
Something to keep in mind:
Loudness of an exhaust is not necessarily a predictor of whether it drones or not.
Drones is not caused by loudness.
It is a result of harmonics from the engine.
Quality exhaust filter drone regardless of being low noise or loud.
On other hand, not so quality exhaust will have drone whether low moise model or louder model.
If not having drone is a priority, you should really pay attention when someone says a particular system is absolutely drone free.
It might be advisable to focus search in that direction.
Something I’ve stated before from experience.
Magnaflow has some drone.
Borla, or specifically, FP by Borla has no drone whatsoever.
Important clues in such words.
And, if you pay close attention to Bill and the AM videos, they pretty much say that too, just not so directly.
If you want loud, Roush are loud.
