Default Ouch, sorry about the cat Adam. Since you're nDBW you "might" now throw a CEL.

But I think it might be smarter to just replace it with a HFC because then you will definately not throw a CEL. If you are like me, then CEL's almost ruin the advantage of the modification. If you are able to clear the CEL, then that is a different story and I would go with a test pipe. Good hunting.
