Can anyone with the 300 L6 or just anyone that has had experience with this can you tell me if this would throw codes or not? The stock system has two cats but this only has one. It says it's 49 state legal so I guess it should be fine for Ohio?

I would check magnaflows website and see if it gives you the same part number. If it does match up you should be good and have no codes. I bet their one converter works as well as the factory pair.
