Should I run dual cats or one cat with LT's? So my car runs dual cats stock [97]. I plan on running LT's in the future and I need to have cats. Should I run dual cats, or just run one cat? I want to keep the rasp down since my car has a Borla system, I think dual cats might be better at accomplishing that over a single cat.

depends on what brand LTs you use. say for instance you run TPiS and a Random Tech ypipe. that ypipe by design has two cats reguardless of if you are OBD1 or OBD2. if you run Mac midlengths you may be able to run one. the biggest problem will be that youll either have to run sims for the back O2 sensors, or you will have to have two bungs put in the ypipe to mount the two O2s if you go with one cat.
