My 06 with Bub7's TD Hope this helps

 

The tdx have 2 pipes on the throttle side and cross under the frame. The other ones route along the primary on the clutch side.

 

Yeah those pics helped. Does the TD produce more heat for the passenger's left foot though? Gotta keep the Ol Lady happy

 

A little heat but not excessive.

 

I put BUB7 true duals (crossover pipe removed) on my 09' FLHX. I found that the rear pipe hits the left side-panel and required a few beers and some late night garage engineering to make it fit without touching my new paint (I'm not impressed BUB). BUB needs to correct that problem since the 09' and later have larger left side-panels. They are louder pipes than the Rhines, and a whole lot louder than stock. I'm currently looking to put quieter baffles in them so I can hear if I'm pulling away from the sirens behind me.

 

I think Rinehart did that for the '10 models with the stupid 12mm heated O2 sensors. That way they could have a true dual setup and not need to extend one of the 02 sensor wires. The stock sensors plug in under the "six-speed" cover on the transmission, not at the heads like earlier bikes.

 

Left side. Not sure if it'll different on your 10 against my 08?

 

I decided to go with the V&H true duals with the Widow slip ons
