Decibel test of a KTM 790 Adventure with an Akrapovic muffler and an Arrow de-cat mid-pipe at varying RPM's under a 15% dynamometer brake load. 790 Duke Akropovic Muffler: http://www.rottweilerperformance.com/akrapovic-slip-on-line-titanium-muffler-ktm-790-duke/ 790 Duke Arrow De-cat Mid-pipe: http://www.rottweilerperformance.com/arrow-ktm-790-duke-racing-mid-pipe/ NOTE: This video is designed as a direct comparison to other videos we produce in the same environment and not intended as a direct decibel result of any kind. The DB meter will also pick up some noise from the dynamometer drum, drivetrain, and tire spinning. In order to offer the most accurate sound under load, these are the compromises. PS: Please don't give this video a thumbs down just because you don't like loud exhausts. We are just showing you stuff. :)
