Default Leak in headpipe

I found an exhaust leak on my 07 rdking classic today while doing my service. I have been having a decal pop last summer, I am hoping this might cure it but don't know how to go about fixing it. It is leaking by the exhaust clamp on the front headpipe before the Y. I tried to tighten by is tight. Do I have to remove and and piece out the whole system to fix the leak, is there anything I can do on the bike without taking it off?

Your head pipe probably has a crack in it near the rear cylinder where the pipe y's. Check it out

I checked for cracks and found none. It is where the front pipe is clamped before the Y. Exhaust is leaking from the bottom of the pipe next to the clamp. I don't know if a new clamp would fix it or would I have to take apart the whole system apart piece by piece to separate it and get to the problem.

I have heard that the 2007 touring Harleys have been known to develop cracks in the stock head pipes.

Time for the Fullsac true dual conversion for the cheap fix or go to a quality 2 into 1. My 07 did the same thing. Could not see it and had decel pop. After about a week it spread to the point where I could see it. Repaired twice under warranty. When it goes again I have the fullsac conversion waiting until I can find 2 into 1 for less than 1000 bux.

Can you get a pic of where you think it's leaking? I'm confused by your description, which you typed twice.

On my 07 ultra it cracked right after the y ,bought a used one at the dealer ($100). Had the old one welded, and now have put that one on and keep the extra on the shelf welded and ready for my sons bike to need it next. The repaired ones have not failed. Seems to be a stress point. Just traded in the 07 for a 12 limited. What a nice change. The limited has V & H slash true duals, and the solid mount has broken, V & H has now changed design and does not support the older design, had to find a used part to put on. Hope this one lasts.
Looking to swap the V&H for Screaming Eagle pipes come spring. I like the drum beat better than the V&H clap.
