Well, some of these engines rattle, and some don't...it because of chinese quality control or the lack of it.
Check the muffler for loose parts. Bang on it with your hand, when motor is cold. Or remove and shake it. Under load the exhaust pressure can keep the parts snug. At idle or cruise the parts jangle. I had the same problem on two of the black, cat mufflers. The long tube goes through two plates, the upper plate was not welded and was making a terrible racket. Sounded like the engine was coming apart. Not way to fix except cut and weld. If under warranty, contact vendor. I need a SBP expansion pipe.
