Zeb...Now that you have installed the PowerFc into your car..you can replaced the whole downpipe with an aftermarket Header unit. But you will have to maybe do some fine retuning..There is not much effect on the sound of the muffler if you removed the cat..maybe slightly louder.But the aftermarket header will add the metallic sound that most extractor have when you rev the engine....IMHO.
