domestic.

wassofunny?  I was born here, trained here, and worked here all my life.

isn't that domestic?  

Is there a landing in the Dyna that stops the header going in"
How far is the header in the Dyna?
I had to grind the header to get the Supertrapp on.
I let sparks get near the battery vent.
I bought a new battery, because hydrogen is Very flammable.

Boy, if it ain't one thing it's another... I wanna get some Ride reports,  instead of
Ohh, maan, it's busted..

How far do the slots go down the Dyna.
Are there enough slots to Allow the clamp to crush it down to the header?
Is your clamp a T Clamp?

The usual headache is where you are, I think. Others have been making shims and using high temp pooky to get it sealed.
I wonder if lead would work..  
You're not wrestling with it on the bike I hope..From what you have said, you're not..

If your clamp squeezes the end of the Dyna down but the edges of slotted area come together before it's crushed down, snot gonna seal.

I would have it off and put the clamp on it and see what happens without a header pipe in it.
The slots are probably long enough to make a good connection, but you might need to widen the slots a bit.

Without any squozing, how much bigger than the header is the unsquoze hole?
I have been seen using a body hammer just by the end of the slots creating a step to get the Fingers moved in a bit.
I don't see a problem with your wide clamp, unless it's wider than the slots. Well, you need some distance from the end of the slot. The more you need to collapse the mufflers Fingers in the more you have to have room between the end of the slots and edge of the clamp.

Hawk,

In my humble opinion, which is subject to review, get a genuine Harley Davidson Exhaust Clamp that you can torque it down as tight as you need it to be.

Finally installed the 94' Dyna w/rail mount. Didn't bolt up like I thought it would. Using the standard mounting holes on the bike the muffler was a full 2" away from the end of the header pipe. I re-drilled the bikes mounting bracket and found that a standard 1 3/4 Heavy Duty Exhaust Clamp from Auto Zone worked just fine in clamping it to the header. Bike sounds good and runs pretty well without tuning the carb as it's over 100 degrees outside & I'm melting! Will see what I can do with the tuning in the morning when it's cooler! FYI - will be selling my extra 94-Dyna in the Marketplace shortly for $60, shipping included (USA only)!
