What to do with the O2 sensor with aftermarket pipe ???

Hi all,

From what i have been reading, Aussie and Euro spec WRR's have an O2 sensor, which the US bikes don't have.

I am thinking of buying a FMF Q4 and powerbomb, what do i do with the O2 sensor??

The bike is totally stock, so over the next week or two when i can find time, i plan on removing all the usual stuff. If i buy an attitiude or power commander will these take care of the O2 sensor???

I am a bit useless when it comes to FI

If your pipe does not have a bung for the 02 sensor just have a welder put one in for you
Easy mod, an exhaust shop should be able to do it in about 15 minutes

If you change your mind on the FMF the GYTR pipe has a O2 sensor bung built in.
I'am not running a power programer as my bike seemed to re-program it's self.

Hi Sam,

I test rode a bike with the GYTR pipe, it was way to loud for what i am after.

Thanks for the input though.

Don't rule out the GYTR too soon it gives a way better mid range and I belive you can get a quiter baffle for it from DRD (can someone confirm this please).
Also make sure you acually hear the FMF your self I havn't herd one for a while but I didn't think it was much quiter then my GYTR.
That pipe had done 4000km in the Kimberleys and was in very bad condition for it's age it's quality did not look good.
