S65 Straight Piped
Guys I have Straight Piped my 19 S65, and it sounds amazing !!!
I will post videos if you guys are interested.
The problem with the step up is that I keep getting the yellow check engine sign. I ran an obd test and it has something to do the catalytic converter being removed triggering the o2 sensor.
I would be grateful if someone could guide me on a work around or a way to bypass the o2 sensor. a plug and play mod would be awesome.
Many Thanks in Advance

I must say I'm curious what that sounds like.
To remove the CEL you'd need either a specific tune or you'll have to install a mini cat not sure if either exists off the shelf for the M279.
If you are in the US you'll be hard pressed to find a shop advertising to do this due to the recent crack down on parts/shops that increase emissions.

This is the best answer - the car was designed to run with the cats on their and, frankly, it is an ******* move to remove them.
