Have had my comlete xrs only exaust on the bike for about a week now .Its louder than I was told it would be , but I am quit happy with it . Monting was better than some pipes I have used .Sounds great now that I am getting used to it. I did put the largest main jet I could find in it .165 dyna jet that came with the kit that I started with. Quality seems very good . I will clean up the weld s this winter.
