I am almost embarrassed to ask this (ok, I AM embarrassed)
I am replacing my side pipes on my '66 s/b and it seems the existing pipes are 2 1/2" which is not stock ID, (should be 2") or at least this is what appears to be the case. This won't be the first time I'm finding more inaccuracies about the car than I was told by the PO.
In shopping for replacement pipes I found these listings for side exhaust amongst the various suppliers:
1965 and 1966 s/b: 2" ID
1965 only in s/b: 2 1/2"
1965 -1967 b/b: 2 1/2"
With that said, I got to the 2 1/2" ID when I measured the ID of the heat riser gasket. I imagine this is a no-brainer way of determining an accurate ID of the entire exhaust system. Am I correct? Thanks.
