Spintechs are chambered at least the ones I've seen over the years. How are the Kooks designed? I would dyno with the mufflers off and on.
In the old 4th gen days we dynoed Flowmaster chambered mufflers on and off, and off the power gain was big.

The Kooks mufflers are straight through with packing. I always liked the sound of a chambered muffler better.

Maybe you can dyno all the choices just so see. I"m just saying chambered mufflers might skew the gains.

I have always heard chambered mufflers as being the best sounding and loudest. But they are more restrictive than straight through mufflers.

I would sacrifice a few ponies to have the sound I'm looking for.

Think of all the great info you can share by making a dyno pull with the mufflers, and then with them unhooked.
