I needed an exhaust for my fiancé's car. The standard exhaust has 2 mufflers and now a straight pipe goes to this muffler. To be honest it sounds a bit louder than the production model and has a quite pleasant tone. I was hesitant after reading the reviews but we wanted to cut the budget as she's getting a new car next year or so. The plan was to put another muffler on if it was too loud, but that doesn't bother them. There are also not many drones on the route.
