Default running open headers

I have hooker super comp LT's and dumped true duals. I don't want to carry the weight of the exhaust/mufflers down the track.

So I know that running open headers screws up the O2's. Would the scavenger turn downs be long enough to prevent this?

anyone have pics of their similar setups?

thanks

I'm running dual-open collectors w/ O2s and have 18" extensions. Also, I got rid of over 50+ pounds with the exhaust removal.

thanks for the pics. I think I'll just end up running a foot of pipe or the turn downs. So that will be enough to keep the O2's reading properly right? When im on the street I will just bolt up the exhaust to keep the neighbors happy.
