Hi all. I've had Yoshimura AT2 delivered to me today and I've a question about O2 sensor. On the exhaust it says it's meant for closed circuit racing, not for the street, so why does it have O2 sensor plug designed into it? It even comes with extender, so it seems like at Yoshimura they want you to run it with O2 readings. And most certainly you'll have your ECU flashed with your full exhaust right? And I've read that if you get your ECU flashed the flasher will disable the O2 at all, is that correct? Or it depends on whoever is doing the flash? And if I'm understanding correctly why bother at all designing the full racing exhaust with O2 in mind...
