flexable hose source

anyone have a source for 3 1/2 and 2 3/4 inch flexable hose? thanks

I remember reading somewhere that a great source for flexible silicone tubing (like what you would use for a turbo or supercharger install) are trucks and trucking supply shops. Apparently they sell the same tubing that any of the big-name supercharger manufacturers sell, but at much better prices and with a much larger range of sizes / configurations.

Also check Ebay, a lot of choices there
