The Pro Circuit Factory Sound 304 Silencer is designed for most types of riding and for riders that want a silencer similar to the R-304 but with a little less noise output, and little more of the power near the top end of the rpms.
That power of the 304 comes from a straight-through design of the stainless steel stinger, end cap, and aluminum canister body, leaving exhaust gases free to leave as efficiently as possible. But because the Factory Sound 304 has a slightly longer canister body than the R-304, sound is reduced as the E-Glass packing material has more time to absorb some of the exiting sound waves. The length also slightly affects the power band by giving your bike a little more top end.
But even with the longer body, the premium materials used still result in a weight that�s much less than your bike�s stock silencer. Plus you get removable hex head hardware so you don�t have to drill out any rivets when repacking. All of it adds up to make the 304 Silencer an excellent option if you want maximum performance with a sound that won�t get you kicked off a track or trail.
