51 S8 Decat?
Im looking at removing the catalysts & fitting a custom stainless exhaust on my 51 S8, and wondered if anyone has had any experience in doing this?
Iv heard that there is an adapter you can buy for the lambda sensors (called a Wayne Angle Block??) and wondered if anyone had tried this?

Several possibilities there
1) bring post-cat lambdas out of exhaust flow a bit either by by using intermediate piece or welding a small piece of metal sheet in front of them 2)code them out of ECU. I have a quad tip exhaust that I won on A8Parts open day and were thinking of putting on my S8 but have changed my mind. Let me know if you are interested. I have posted some pics in this thread: http://forum.a8parts.co.uk/showthread.php?t=4775
