Query about particulate filter

I not too long ago bought a tune by way of MHD for my 19′ F22 B58.

With a view to go stage 2 you want a excessive movement dp and no Gasoline Particulate Filter.

I’ve heard blended data on-line concerning the GPF so simply making an attempt to determine the place it’s positioned and what’s essential to take away it ?!

I noticed one thing stating that’s positioned in my resonator, so do I simply must do a res delete?

Any perception is appreciated!
