You'd like the sound from the mod
I just did perhaps, converted my MCS
to right side exit 2.5" stainless cat back with resonator and single silencer (not very big) 3" outlet. 1/3 of the weight if that, but too loud for me, and just did it to test, others like it though. I wouldn't decat personally, but would use sports cat, and for me the resonated as you have, without it would be louder, but it's difficult as you don't get demo's on exhausts really. Looks better imo.
