Although you can buy it retail, I believe you can also buy direct from the manufacturer. They're a growing company out of California. I don't know if they ship internationally, but I'm sure you can write to them directly.
I would obviously recommend a Firebrand slip-on, but Speed Merchant is a good company with good products. If you go through Revzilla.com they do a program with freight forwards to get products to India. You can buy Firebrand and Speed Merchant from them. I dont know exactly how it works but contact revzilla.com and they will help you out.
