Agree more details are needed. It is a February 1972 build and has the stock ansa webbed headers, but I do not know the vintage of the ansa muffler assembly. It is a high pitched chirp. Almost sounds like a belt chirp but seems to be coming from the muffler internals as I can turn the noise on and off by blocking the same outlet on the muffler. I’ll see the car again on Monday so I’ll investigate further.
