How will running true duals affect the o2 sensor?

I have a 1994 F150 4x4 5.0 with an E4OD. When I bought the truck a previous owner had already hacked the exhaust up so there is no catalytic converter. I have been thinking about running longtube headers with true duals through a pair of magnaflow mufflers. I noticed on my stock y-pipe that the o2 sensor is reading from both sides of the exhaust. Will there be any difference if it is only reading from the passenger side exhaust?

No it will work fine, the computer treats all cylinders(injectors) the same anyway.

On a side note, you can always go 2-1-2 and save some money and the headache of routing 2 pipes all the way out the back. Are you going to have a crossover?

I vote for single 3 inch pipe with sinlge in dual out straight through muffler and 2.25-2.5 inch talpipes with your choice of 3-3.5 inch tips. It will flow nearly if not as well as the true duals.

Possibly even better with a single pipe. Less head loss.

Go with the duals,imo it sounds way better and you get a deeper sound.I've never had a loud ford truck with just single exhaust.But that's just me I like a loud aggressive sound.Login | Facebook

This is my truck at silver lake climbing test hill.At the time I had shorty headers,2.5 pipe back to 2 40 series mufflers with 3 in tailpipes.The sound on the video kind of cuts out,but you get a general idea what it sounds like.
