Vance and Hines Power Duals Installation

[Terrymac]

Hi

Hope someone can help me. I am installing a set of power duals on a 2015 Street Glide. In the instruction manual it says to remove the two O2 Sensors which is no problem. On the right hand side pipe just before the muffler there is a wire operated butterfly valve installed inside the existing header pipes. The new Vance and Hines headers do not have any provision for this valve. There is no mention of this butterfly valve in the V & H instruction book

I already have fitted monster squared mufflers to the existing headers and have the fuel pack fitted. I am assuming I just remove this complete assembly or gave I got the wrong set of headers. Any help would be much appreciated

PowerDuals are a straight-forward install... whatever you have there is not needed with the Powerduals. You may not be able to remove it and all associated components as it's most likely a part of some other international setup.

Just curious though... snap a pic and post it for general knowledge.. thanks

EDIT: After a small amount of research...

You are in the UK!!! I am unsure if this is something for the overseas bikes only as they are NOT on US bikes.... More information would be needed on this to shed some light on it and it's purpose.... I believe it's on European models for noise control operation thru the ECM

Pics would be much appreciated.

Hi hope you can view these two pictures the butterfly valve is only on the right hand header and looks to be going up to the ecm and is wire driven on a cam

That definitely looks like the noise reduction unit for European models. There are some writeups on them on the web... not sure if they are all the same. Not sure if you can just unplug it, but look and see. If you can... throw your slipons back on with the cables holding it open and fire it up... see if you get any codes that inhibit normal operation

I ended up removing the wire off the actuator mechanism fitted the whole system back and used the fp3 to remap the ecm and fired up first time and seems to run ok


The other problem I had was v and h supplied two cylinder gaskets which were virtually impossible to fit. The existing head pipes had no gaskets. I tightened them up with no gaskets and the bike is running with no leaks. Have yet to road test it though just wondering if anyone else has tried fitting these wire mesh gaskets with any success

Thanks for all your help

The gaskets are there, they are just pressed in and derformed into the jug by the pipe. If you are not leaking... call it good. if you get a leak, the pipe must come off and clean the exhaust ports of the old gaskets and replace them.

I could not see any signs of gasket when I removed the two header pipes from the cylinders but the original pipes had a tapper on them. The new V and H pipes are a square ended fit with now tapper. Fingers crossed I don't get any leaks kept the gaskets just in case. The gaskets supplied do not fit inside the cylinder exhaust ports and would have to sit flush on the cylinder manifold lip which is a nightmare to line up

Thanks for all your help and valuable advice
