Vibrant resonator question/advice (rasp)

Hey guys, so my car is a 2007 335 coupe fbo minus meth.
My exhaust setup is: Bms catless dp, and 335is mufflers. I love the sound and everything, but the rasp/canny/tinny sound after 3500 rpm is way to obnoxious and ricey for me and I don't like it.
Question: my idea is to put in vibrant resonators 1792, should I add them upstream in front of the secondary cats? Or should I remove the secondary cats and put in the resonators, or just keep both.

I'm scared that by removing the secondary cats and switching for the vibrant resonators it'll get louder, and I don't want louder as it already loud as hell. Any input will be very appreciated. Thank you.

IMO remove secondaries and put in the resonators in their place.

That's what I plan to do anyway.

Good luck!

I'm fully catless. The sound was too harsh so I replaced my secondary cats with vibrant resonators. They removed the rasp and cleaned up the sound. You'd be impressed with the difference.

Did it get louder when you swapped the secondaries for the vibrants? And do you notice more emissions smell and smoke? I just don't want the car to get louder

I can't answer that because I gutted the secondary cats long before I swapped them out for resonators. So, in my case, the resonators made the exhaust much quieter.

Has anyone tired to fit the resonators right after the secondary cats? aka before the X pipe.

Of course you'll have to modify that brace.. or the Y brace for some people.
