Question New muffler... breakin period

So i ran outta money, stupid gas attendant put gas in my diesel box truck... so i went cheapo and bought the thrush turbo.. after putting it on it gives a nice rumble at idle but once i get over about 2k rpms it sounds stock. Is it just the thrush or is there a break in period?

My Thrush Turbo has a nice little rumble at idle as well. Mine drones like mad at 42-45 just after the shift into 4th. Over 50mph it quiets down a fair amount. I am pleased with mine.
