Decat & GPF Delete

[Neaky290]

Has anyone done a Decat and GPF delete on their Cupra?

I've seen a video of someone who did both but left the res in and had a back box delete, car sounded insane but probably a tad extreme.

I was thinking Decat and GPF whilst leaving the back box in place, res delete is already done.

Anyone done this?

Thanks
