This is a long-tube exhaust header for Fiat and Pininfarina 124 Spider. The components here are tailored for 1975 or later North America cars with right-side catalytic converter and the header assembly has an O2 sensor port for Fuel Injection application on 1980-on 124 Spider. Fully compatible with earlier 1975-80 carbureted cars if the 02 sensor port is plugged or used for a wide-band Air Fuel Ratio sensor.
2-1 downpipe is mild steel, with dog-leg for catalytic converter fitment as applied in 1975 and later cars. Includes a 1980-on square end flange for later 4-bolt cat converters.
1 3/4" collector / outlet.
NOTE: The downpipe has an intentional divot from the manufacturer to ensure clearance to the steering linkage. Factory issue downpipes for 1980-85 FI cars have this same exact indentation.
Or, just "roll your own" converter-delete center section pipe back to the exhaust muffler.
