Don't know if this helps......I just ordered VnH big radius 2I2 for $497 w free shipping. This was the lowest (seemingly reputable) offer online. I'll post with my experience when they arrive.
I paid $419. plus tax at my local Harley dealer and they were in stock. With shipping costs the online sites were more expensive and there was a wait for shipping.
Get the part number from the Vance and Hines website then hit up Amazon. You'd be surprised. I shopped around and actually found my V&H the cheapest from a seller on Amazon. It's a bit nicer when you're going through a giant intermediary.
Check out Direct Harley Parts. I always seem to get the best price there. Just checked and they are cheaper than DK and anybody on Amazon, and free shipping.
