My car doesn't run as good with the new converter but I guess it's better than having a check engine light. I was burning alot of fuel with the high flow converter so it wasn't worth it.
Could you tell me which cat. converters you've used and how their power was and if they threw a CEL? And which new cat. did you use that didn't throw a CEL? Thanks!
