could anyone suggest another alternative to factory catalytic converters to improve
flow

I've just rebuilt my car's engine and discovered in the process that both (2)
catalysts were plugged, plan on purchasing two aftermarket replacements but am not
familiar if there are better parts or performance parts available and if so, where?

will gladly accept suggestions for online shops or specific parts

There's probably not a complete aftermarket high flow exhaust for that
vehicle (I was thinking maybe you had a Mustang or something for which
direct-fit high flow cats are available) but you might want to check
with Walker or other exhaust mfgrs. to see if they make a universal
high-flow cat that will fit your exhaust configuration.
