I have a 2015 v6 only mod is the Roush AB. Everything else stock. It drones a lot. I love the sound and the loudness of it, so changing setup isn’t an option for me. But while cruising on highways it gets very annoying. It feels like a sub-woof blasting medium to high level. It rattles my whole cabin just like when the space ship lands while watching a movie in a theater. I live outside US so i cant refund, i need to fix the issue. I was wondering if somehow i could fix this by a Res delete with an x-pipe/h-pipe. I’ve also heard about hemzholt res (capped empty tubes with variable lenght). Thanks in advance.
