Vance & Hines Power Duals
Need a little help understanding - Just installed Vance & Hines Hi-Output Slip-Ons with Power Duals and have some concern one side of the Hi-Output Slip-Ons is running hotter than the other (left),More Air comes out of the same side, a lot more (left)Also the tip of the Slip-ons is turning Yellow,(which cleans right off) is this normal? Will it go away?
I have called Vance & Hines and Tech support telling me all this is normal for this system and the yellow stuff after time will not happen- any feedback out there

Have the Power Duals and Monster Rounds on for 2 years now. Had the bike dyno tuned by a good tuner, and have the same condition on my bike. Seems to be a normal condition. Bike runs great.

It's ok, it's all normal.
The left side gets more exhaust flow for some reason and will discolor quicker than the right. Mine started out a dull yellow at first and then black with carbon. I'm running a very rich map so black is normal. For some reason the X pipe scavenge system creates more flow to the left side. Should be some technical reason but I haven't a clue as to why. Your system sounds OK based on what you describe.

Guys I have the power duals for over 2 years now and my bike has been dynoed tuned and both sides seem the same on mine. They are a awesome pipe though and make alot of power and tq so I wouldn't worry. I would suggest getting a tune done though.

I have the same setup on my Limited Ultra --- Power Duals & High Outputs, and they do the same thing. I talked to a guy at a dealership once who had the same thing on his, so I was aware of it before I put them on. The bike runs great, and I'm not worrying about it. It's been like this since March or April when I put the High Outputs on, and haven't had 1 problem or issue.

Mine does the same thing. I was told by the dealer it is normal and the bike runs fine.

Never noticed this but now I will have to check it out. I love the way my bike runs though so I won't worry.

Same thing on my 12 Limited. Actually I took the bafflers out of the Monster Rounds and swapped sides to balance the color. Again as stated in most replies, very happy with the pipe and muffler combo
