I've got a straight piped M6 there really isn't any droning issues. What a lot of people fail to realize is how much the turbos doe absorb noise ahen your just cruising.
If you don't own one of these you don't understand exactly how much sound really gets blocked out these cars are built awesome so they have a cabin that makes it harder to hear whats around you . Even a semi is quiet
*1st Car: Muffler Delete System. 2nd Car: Resonator Delete System. Both cars STILL have their converters on. So that’s NOT a straight pipe exhaust system*
Drone city, all day EVER-REE-DAY...! There has to be a muffler or resonator that gets rid of that muddy, guttural tone those BMW twin-turbo V8s have. It's been the same thing for the last 15 years. You guys made it louder, but not necessarily better...
Muffler cancels out rhe drone, resonator doesnt even do much. On my bmw the drone got noticeable less with removing the resonator. Here I‘d say you shouldve kept the muffler, has a valve anyway
