One of the tuners or vendors should be able to tell you whether that will work on our cars. Good question for someone from BMS.

It will work on any car (just get the better quality one so it won't rust). Post cat 02 is for cat efficiency only. I've used the extender on 40+ cars and it worked 100% of the time for catless downpipes. "Off road use only" |
I think I saw a post of yours in another thread about the o2 extender from amazon. Is that the one that you use on your cars? As long as it wouldn't mess with the ecu, I would be willing to take a chance if it working since it's so cheap.
