How to eliminate rasp on 330 (with headers & racing cats installed)

Hey guys,
I've recently installed schmiedmann headers & cats. I have an eisenmann race muffler on the car prior to the headers and cats.
After i installed the headers & cats, my car became raspy (especially at top end). Sounds exactly like a stock m3 . I know some of you guys love the rasp sound, but personally im not a fan.

So my question is, if i replaced the cats with the oem section 1 resonator& cats (note that my car is euro spec therefore has cats in resonator section 1, will it eliminate the rasp? Or is there any other way to eliminate this rasp?

The kind of sound i am looking for is the deep throaty sound that eisenmann race mufflers give or will i never achieve that again since i installed headers?

i know by just installing the headers and nothing else, the exhaust produces the raspy sound, as seen in this thread

Thanks for taking the time to read !
