A new catalythic converter typically costs $350 (material + labor). I paid $650 to have both main cats replaced on a Mercedes, which had a 5 liter V8 (much bigger engine than your Kia Soul).
Pros: good price

Mercedes
MagnaFlow high flow cats are quality and inexpensive

Pros: no check engine lights
Cons: faint exhaust smell
Vehicle:
Acura Integra
