Cupra 290ST res delete reinstall

[Tinbum51]

So installed the rear section of a Carbon ST quad exhaust onto my 290 that has a res delete.

Just cruising it’s lovable, but under hard acceleration the booming inside the cabin is too much, i think from back pressure build up.

Been advised should reinstall a resonator to rectify (original or cherry bomb M80 muffler in centre section.

Any advice if this is will help tame the boom without losing any power?

TIA

You can buy a resonator delete with a 'helmholtz resonator' which improves the drone.
