Help Identify Akrapovic Racing muffler for KTM EXC-F 250/350

[wiledog_X]

Hi there.

I was given this new Akrapovic KTM Racing slip on muffler, and want to sell it but can't find the specific model to determine a price.
I think it's an older model - can't find this specific one.
I googled the part number, barcode etc. No luck.

Anyone have an idea?
