Any racers out there runnin' both in your header collectors and where are they positioned? I'm concerned with contaminating the o2 sensors by having them downstream of the pan e vac tubes.

Thanks
 
I had my Tti headers setup by Tti with evac nipples that I capped off. In retrospect, I probably should have had them put O2 sensor bungs in them because that's what I'm using, with the Innovate Motorsports dual wideband O2 system, and I may never run evac tubes.
Great question though, so I'm :popcorn2::popcorn2:
