This would not be the case with Akrapovic catalysts or HJS units. 100 CPI cats were tested during the prototyping phase of the MRF pipe and saw no difference in power and volume. The only aspect of the system that was affected was overall weight and it reduced a small amount of rasp, however overall volume was not changed. The MRF Velaforza mid-section was never produced with catalysts and never will be.

I've talked to Malek quite a bit regarding how they set up in prototyping, and he said it was done with cats in the primary position.
