Cats vs catless pwr and rpi gtm noise?

[Craze]

Hi currently am catless running ess tune and rpi gtm exhaust full straight pipe

I’m wondering if anyone can help me with the following?

Will going back to cats stop the slight drone at 1500-1800 on rpi gtm exhaust?

What power difference would it be going back to cats and or if i went high flow cats or is it not worth it?

I know catless used to be all the rage

Thank you!

I get drone at low rpms with cats and straight pipes.

Cant help you with power but I can say if I change my downpipes it will be with 200 cell catted pipes less disadvantages than with catless.

It's only really noticeable at around 60mph, it's not the worst but definitely gets annoying. I straight piped my original exhaust so I still have the valves, close them and the drone is gone.
