When I first got my bike I had the stage 1 download from the dealership. I noticed tonight while pulling codes from my bike it shows the part number 34462-11A, this is the calibration number for stage 1 download. My question is, if this "part number" is for a 2-1-2 pipe like the part number shows, I can still use my new V&H Dresser Duals....right?

 

it won't hurt to try it but it won't be 100% as that cal was disigned areound stage 1 a/c and stock headers with slip ons. It might run great tho so give it a try.

 

I believe that is your ecm part number.

 

When I looked up the part number it comes up as the stage 1 download 2-1-2 exhaust.

 

Thats the part number for my stage 1 d/l,I am running a decatted headpipe with a SE air cleaner with Wild pig pipe slipons on my 2011 FLHX.I've also added the Flvied10 from nightrider and it runs pretty good.No decel pop and good throttle response and mileage has'nt suffered much.

 

you are correct that is the stage 1 dl part# for 96" se a/c and slip ons.

 

H-D downloads are designed to be compatible with specific H-D parts, nothing else. Invest in a tuner.

 

I should be fine with Dresser Duals instead of the stock 2-1-2 head pipe....right??

 

you won't know until uyou try. it most likely will not be 100% as was stated your stage 1 cal is specifically for se a/c and stock headers ie with cat and slipons. your tru duals will change the breathing a bit. it might work fine it might not.

 

When I had the stage 1 download, I told them that I would be upgrading my head pipes eventually. But the download part number states 2-1-2 head pipe. Do you think I could have the dealership make the change to the download???
