Exhaust question

I've got 2015 2ss / L99 and have kooks LT, Airaid CAI, resonator delete, HF cats, tune, then had shop fabricate the x-pipe back to stock mufflers. I like the sound, low rumble until you get on it. I was recently told though that the stock mufflers are/would restrict the air flow too much and something like a corsa/borla/etc muffler would open it at least 40% more and add a little more HP and be better for the overall flow. Has anyone done anything like this or know how accurate this is ?

No. The stock mufflers actually flow really well. The only benefits you will get from swapping them out is more sound and some weight reduction.
