Best options to replace Catalytic Converters?

B5 S4/RS4 - audizine.com
Need to replace the cats on a 6spd 01 S4 due to low efficiency codes. The car is stock and want to keep it stock or as close to stock as possible. What's the most cost effective way to replace the cats? ECS Tuning has refurbished units for $1000/per side, but I also saw magnaflow has direct fit for $500/side which claim they are made to exact OE spec.

What are my best options? Thanks!
