Description

Iconic Spark muffler, super aggressive, the same muffler is used on the Moto2 and Superbike World Championship tracks without dB limits.

This last proposal is extremely appreciated in those countries where there are no deciBel limitations and it is supplied with the hanger to the original passenger footpeg. The bracket to chassis is optional. The db killer (G9980) is already included in the kit.

For all the proposals above, the diamters and lenghts optimization of the collectors ensures a strong increase in maximum power across the entire curve
