LFX with MRTv2, remove 2nd cats?

I just read a lot of threads talking about the secondary smaller cats, but I never really found an answer about removing the second cats with an MRTv2 setup.

I know the HP difference if any is negligible, I'm mostly just wondering about the sound.

Would removing the secondary cats make the MRTv2 setup a little louder? Even noticeable? Will it just add rasp?

Is it so negligible that it's not worth the time and fuss?

I currently have the MRTv2, CAI, PTB, V throttle controller and love it, but just wondering what other small things I can do!

My guess it will be a bit louder and add rasp since the secondary cats act more like a resonator...the mrt v2 sounds great by itself..I've heard it with a resonator delete and it just added rasp, didn't really sound good in my opinion..I was running dynomax bullets for a while and it sounded good, then I regret doing a resonator delete, this just added a lot of rasp..I just re-did my exhaust and went with the resonated x-pipe and 2.5" piping to the back..so far I'm satisfied..it has no rasp and sounds deeper..

If the negativity of the added rasp is greater than the positive of being louder, I guess I'll just leave it alone.
