My current setup is:
JDL 4-2-1
2.5" stainless OP
Factory FP
3" resonated Perrin CB

(What I'm looking for is some personal accounts of what would be effective to reduce dB's, below is my context)

I originally opted for a 2.5-3" transition FP but was entirely too raspy. So I reinstalled the factory FP which helped tremendously but is still too loud for longer sustained trips.

The crossroads I'm at is chopping up the 2.5-3" FP and welding in something that will be quieter than stock. I'm just not sure what that would be. I'd prefer to avoid a cat to keep it free flowing for the sake of the SC, but I'm open to the idea if there's some first hand accounts that a resonator/s won't have the desired effect.

The option I've been looking at is some Corsa resonators. The length of the FP would allow for as many as 2 full sized and 1 stubby resonators if it took that much. The long 3" is rated at a 6-8db reduction, long 2.5" at 4-6db, and a last resort addition the stubby 3" 2-3db.
My question is how would this compare to the factory FP, or to using cat/s? The last thing I want is to spend a few hundred dollars in resonators just to be equal to or worse than the factoy FP.
