I lucked into a set of old pipes with a removable cap on the end. But when I was looking, I considered going with some of the Asian (Thai or Vietnamese) repops that look close to original, or at least old looking. They seem relatively cheap, but I honestly know nothing about feedback on em, but that's what feedback on Ebay is for I guess. JC Whitney exhaust tips for VW bugs was something else I considered -- someone here used em on a 350F -- but the diameter might be off and you might need to use something to convert it.
