1975 308 gt4 single or dual exhaust?
Hello, looking to purchase a 1975 308 gt4. One that I am looking at has a single exhaust, instead of the dual exhaust that I have seen on nearly every other model? Can anyone enlighten me on if this is unique to this year or model, an option, or is it missing 1/2 the exhaust? If it is standard, does this affect the performance. This car is located in the US, I have only seen photos of one other gt4 with a single exhaust, located in Europe. Thanks for your insights.
