flowmaster "drone" real bad back inside the car, see lots of those for sale on craigslist that people have taken off. They are trying to get a few bucks out of them so they can get their next non-drone mufflers of choice.
That is why I like the 50 series delta flow Flowmasters. Huge difference in incabin sound. You can talk inside the car and not have to yell. Almost no drone.
