Opinions on changing my exhaust?

Luckily, that means the exhaust is fine at lower rpms and highway cruising speeds. But, I am sort of regretting having purchased the DT-S which does not have Helmholtz chambers (closed canisters on side of mufflers to cancel out drone frequencies).

PS: Just be aware that aftermarket exhausts are usually louder than stock and that inevitably means some drone somewhere in the rev range.
