True Duals and o2 sensors

Moving O2 sensors out of exhaust stream with an adapter will infact make ECM adjust
fuel mixture to a little richer then before the adpater was installed. That is because the
O2 sensor is out of the hot exhaust making the ECM think engine is not fully warmed up, like when you first start up in the mornings it runs richer for a short while. pulling
the O2 sensors back out of hot gases with an adapter makes the O2 sensor tip just a
little cooler.

I really didn't want to throw anyone under the bus but...I live in Lancaster right down the street from MGS not only did I buy my true duals from them I had them Dyno my bike. My question is if they work better in that location why the hell did they dyno my bike with the o2 sensors in that location? I know what the OP said but I was waiting to see what MGS said... I could have gone right down there and asked them but In this case I think it needs to be addressed on this forum.

The pipes are great, They sound wonderful, put out pretty good power and are sturdy. the instructions well...plan on having your laptop ready so you can find a install video that a guy did because without that plan on another 6 pack..Putting the rear head pipe on is lets say a challenge...Wait until you get to that point and you will see what I mean. All in All they are well worth the money and I always try to buy from local business. Every guy in the shop is nice and helpful Chris actually dynode my bike as to why I'm in shock at this point.

Give the shop a call. If your bike was dyno-tuned, you don't need your narrow-band o2 sensors, so it wouldn't matter if they were up front, back, sideways, or not there at all, your bike is no longer operating in closed-loop. Moving the o2 sensors to the 18mm position up by the heads is mainly for the guys running wide-band o2 sensors or using an auto-tune.

Even with the old style tuner? I don't have the power vision. I have the power commander...
