-Emissions control: emissions control is significantly improved using suitable model-specific measures in order to comply with more stringent exhaust emission standards.
-Sound: rich sound at a reduced volume; the sports mufflers thus comply with the more stringent regulations regarding noise emission (the limit values have been reduced by approx. 2 to 3 dB(A) depending on the vehicle segment with regulation UNECE-R41.04.)
-Design and weight: the technical changes effect both the shape and weight of the sports muffler.
-Most importantly, this has NO effect on power or torque
