I ordered the Vance and Hines Dresser Duals and CFR Slip Ons from Iron Aces Speed Shop this past Friday along with the Micro Tuner from Fuel Moto. The tuner will not use the o2 sensors.
Later on I may upgrade to the Power Vision so my question is if I want to install the o2 sensors in the Dresser Duals will I need an adapter for the head pipe? The description says it has the ports but don't know if the size is correct size for a 2011 Limited. I know I can check with Vance and Hines or Iron Aces tomorrow, just wanted to know tonight.
Anyone out there have these headers with the o2 sensors installed?

Thanks

 

I have the dresser duals on my 09 and the o2 ports were in the proper location with the proper size. If you ordered for the correct year model they should have the ports in the proper size and location for yours. When you go to an auto tune set up, the kit you order should be compatable with necessary adapters I would think, until then you can plug the ports or leave your sensors as plugs and install the bypass adapters in the electrical connectors to your sensors.

 

Depends on the sensor used. If your tuner uses the larger sensor (like the Thundermax) then order the '09 model year Dresser Dual. If it uses the smaller, newer sensors, then order the Dresser Duals for '10 and up.

Why would you buy a tuner that doesn't utilize O2 sensors anyway??

 

Ditto. I have dresser duals on my 2011 Limited and all is good. I do not have a PCV. I went the way of Screaming Eagle Pro Super Tuner
