That's the exhaust that I thought that I wanted, but at the time found they were backordered by everyone. I ended up with a Leo Vince carbon and I'm very glad the V&H wasn't available. The LV is great and includes the dB insert. That's extra with the V&H, making the price difference less. The LV is more expensive, but well worth it in my opinion.
Anyway, to answer your question,
www.pipecity.com seemed to have the lowest prices on all the pipes back when I was looking. Several of my friends have purchased more than one exhaust from them and are always their first recommended source.
On my purchase, they had excellent customer service and the best price. I haven't checked elsewhere, but they have it in black for $450 today, $400 polished.
