This is a long-tube exhaust header for Fiat 124 Spider. The components here are tailored for 1975 or later North America cars originally fitted with right-side catalytic converter.
2-1 downpipe is mild steel, with dog-leg for catalytic converter exhaust routing under the right-side seat as applied in 1975 and later cars as shown.
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 have this same exact indentation.
Just "roll your own" converter-delete center section pipe back to the exhaust muffler.
Condition: NEW
New and unused.
