Reduce Rasp without making exhaust Quieter

So the Vibrant resonators seem to be a popular choice on here, but I wanted to reduce rasp without actually making my exhaust any quieter. Would anybody have a recomendation for a small resonator that may be able to help me with this?

BMW Performance Exhaust is rasp free, but once you add downpipes it becomes very raspy at the top end.

I am only adding the downpipes for the sake of making my exhaust louder, but if the resonators will quiet the exhaust back down to the same levels as stock downpipes then the mod is worthless to me.

No worries there. They won't quiet your exhaust much if at all. They'll just reduce rasp.
