I'll curious to know if it makes your car run rich from getting false O2 readings or if you still have good power. I'm afraid, like said above, any gains you may get from the high-flow cat, could be lost from the defouler messing up your O2 signal. I'd personally not weld in the defoulers in case you decide to remove them and use normal O2 bungs.

The problem is though is that the O2 sensor is on the stock cat and I am removing them. To be honest with you, the purpose for this is not at all for more performance or power. I hope I don't lose any as of from what I have now, but the main reason is to get a bit more volume and change the sound up

When I said downstream is in the cat, I forget this is s550 and not just ecoboost. I'm not certain about the GT, but my ecoboost downstream sensor is in my cat. If you want more sound, upgrade the muffler. They muffle the sound. The cat makes VERY little difference with sound and lots of difference with pollution.

What's your take on this video ? To me I can hear a definate change . And in all the videos I see its the same result by going high flow. Little more volume and gains more clarity, less muffle ans get nastier lol .
Forward the video to 1:05 and then high flow if 2:45

The original "catted" part of the clip is loudest. The open headers part was quieter, when in reality we all know that would have been obnoxiously loud. He clearly gave it more throttle when driving away after removing the cats, while it was obviously a light cruise down the street in the first part. It's a sound clip from a cell phone recording. I'm not personally impressed.

I'd not for the sake of volume there is a very very noticeable difference in the sound . Which I personally like alot . Sounds meaner
