I know there are two different exhaust system for 1.7 and 2.0 (not mentionning the late 75 with cat that fits both 1.8 and 2.0) ...
Why did factory decide to change the old system (1969-1972 - 1.7) for the new one (1973-1974 - 2.0) ? There are no obvious upgrade to the exhaust, same diameter, about the same length. Trying to understand ... has this something to do with the sideshift change ? |
