Wrapping the perforated tube (it's not a baffle) all the way will help deaden the sound. If that's not enough you could cut the perf tube off where it is welded to each end and rotate it (and re-weld) so that the louvers face towards the gas flow - that is so they will intake the gas flow much more effectively. That should make a significant difference.
Cheers, Richard
