To occupy my day I decided to mount the two new mufflers that I have for several months I made a matrix diameter of the tube to be mounted (61,1mm) I think going to work with public transport until the end of the week, the noise has become spooky in cities, especially in acceleration up to more than 5000trm, I go silent exhaust coming Saturday. with these exhausts the problems of ignition and tranmission rattling noise also disappears and the power increases.
