My car just threw a code for the catalytic converter and I’m thinking of getting Turbo XS High Flow Catalytic Converter pipe. Would this fix my issue? Also will it still throw a code?

Consider the fact that this code can also be (and most often is) caused by:
1. Gross exhaust leak prior to the rear O2 sensor
2. Malfunctioning rear O2 sensor

I'd start there.

This
Turbo XS High Flow Catalytic Converter pipe.
Would require additional engine mapping.

Okay, should I just replace the rear O2 sensor?

I’d not. I’d troubleshoot the above causes first.

Wait — is the sensor even present?!

Since you’ve swapped exhaust why have you not eliminated the code via napping? (I must be missing something?)
