Hi eLBo,
There are two main styles of Harley header headpipes, one is conical like the factory exhaust, the aftermarket style is just a ring welded on the pipe that the retaining ring rests against. The factory system uses a conical gasket that matches the cone shape at the end of the pipe, the other style of gasket is flat and is used with most but not all of the aftermarket exhaust systems. the two types of gaskets are not necessarily compatible.
Who made the pipes have broken and what style were the headpipes?

Thanks: Mike

It's a 2 into 1 system. Because of my affiliation with the manufacturer, I would rather not disclose the brand. They have replaced the headers twice... To take care of me.

Hopefully these will help. Sorry they aren't better pix. The red arrow in the last image shows the only other mounting point, aside from where it mounts at the heads.

The muffler isn't "ridgedly" mounted to the frame is it? That won't work with a rubber mounted engine...at least for very long.

There is a solid steel bracket that runs from the tranny bolts along beside the swingarm, that bolts to the muffler.

How are you installing it? Header first, and tight, then the muffler?

For convenience, I have been connecting the muffler to the header before I mount the system to the bike... But, I have been leaving the muffler clamp loose until the header was all bolted up.

Try getting the header in and tightened first. Make sure it's sitting on the gaskets right, and once it's mounted and tight, work your way down.
