duncan fat boy

[ny300exrider]

im buying a 400ex tommorow and its got a duncan fat boy exaust on it. is there anyone out there that has this pipe and can you tell me about it? also im concerned about the loudness. i know this pipe is going to be extremely loud and im bit worried. is there anythign made by duncan which can quiet it down alittle bit. if not i may have to sell it and swap with somethign new like an hmf. thanks for all the help

i think theres a quiet core

HMF will be just as bad. Duncan does offer a turndown kit with a spark arresator. im not sure that will really help. if you want a quiet pipe that makes power go with the big gun quiet series.

ill have to check about a qiuet core..i hope they make somethign like it.i said hmf as an example since they make the quiet cores but big gun quiet series are also very nice. thanks
