Merriam-Webster dictionary says the word dates from 1957, and may be an alteration of yoicks. Yoicks dates from the 1700’s, and was used as a call to encourage foxhounds. It doesn’t indicate where it came from.
The American Dialect Society had a thread on this within the last year or three. While there was a general lack of real proof, the next version of the OED will have a cite from 1955 testifying to yipes. All early references are to US sources, rather than British.
