It totally goes away in about 3 to 4 thousand miles
When the mufflers get nice and carbon lined you will see the slight drone you have with be gone. It does take a few miles but it happens.
I was lucky because I installed my Magnaflow streets and took off to Pennsylvania to the American Muscle show from Daytona the next day. By the time I got to South Carolina my mufflers sounded way deeper and better then I ever thought they could. No Drone at all. A nice deep rumble.
I now have about 16,000 miles on them and they sound perfect. They sound just like I want them to sound. Nice and deep and just loud enough to make driving enjoyable.
