I have the Greddy Ti-C on my EVO 9 and since I have the extra port for the O2 on the exhaust I installed the wideband O2 sensor in this position. The thing is that the bung is kind of angled out and the sensor doesn't protrude all the way into the exhaust gases. I'm getting a 14.5-14.9 at cruise speed and dips to 10.9ish at redline, does that sounds about right for a stock tune, w K&N drop-in, megan downpipe, and Ti-C?

 

That's fine.

 

Anybody else have any insight on this?

 

when i had mine ti-c i had it in the same location-you're fine,i changed it to megan one and i tell you that i can feel the difference big time...it flows better then the ti-c one,greddy exhaust has to many bends compare to any straight through design

 

I don't know about a "big difference".

 

change it and you 'll know

 

No thanks, I'm good. I'll stick with a well known Japanese company than a Ebay Chinese company anyday.
