So I am trying to figure out which system is better.

I am not doing any HP upgrades other than what I currently have already, which is the following.

2020 Ram 2500:
EZ Lynk with CTT Tuning Emission intact tune with trans tuning.

*Plan to delete EGR and cap wi5-inch exhaust system*

I do plan to do the CP3 conversion kit from industrial injections but I wanted to know if I can get away with doing the front and rear cat filter upgrade with Black Market Performance.

Or go with the FASS system upgrade lift pump.

Pro/Cons and why, if you guys can direct me in the right direction on this choice.

Thanks for the help guys.
