From what I understand it's quieter than the fat cat . hopefully somebody chimes in. I bought my bobcat without hearing it and have no regrets. I remember going from stock at first startup in the dyno room was a holy **** moment.
I'm running the Boss fatcat with what I think is the perforated wrapped baffle( bought it used) . I'm thinking about swaping one muffler for the other. D&D says its quieter with little to no HP loss.
