You can weld a bung on each side of the exhaust, verify both sides are essentially equal, or not and then leave one side plugged. Use anti-seize on the bung threads, but be careful not to get any on the O2 sensor tip.
OMG! Thanks.... I didn't think of that.
The instructions state that the sensor needs to mounted 18" past the collector (I should have mentioned that earlier). In my case that is where the x-pipe starts.... so I thought it would be best mounted just after the x-pipe.... after both pipes have merged and exhaust gases have collected together.
Sounds like I'm a little over concerned.
What is the ideal afr at idle? My Dodge ram stays right on 14.7 most of the time but however it is EFI.
Also what about cruise?
By doing some research it seems everyone has different afrs in mind on the subject.
