1968-1985 Fiat 124 Spider, Spider 2000, Pininfarina exhaust guide
(for North American specifications cars)

1968-1974 124 Spider

These cars all have a two outlet exhaust manifolds connected to a 2-into-1 downpipe.These are good for a stock engine or mild performance engines.For medium to hot performance engines our Abarth type header works very well.The pipe size of the middle and rear mufflers stayed the same even as engine size grew.We recommend upgrading to our larger diameter pieces which were stock on the European market 1800 Spider.

EX5-470 Downpipe for 1438 and 1608cc engines

EX5-474 Downpipe for 1592 and 1756cc engines

EX8-428-Z ANSA twin chrome tip muffler (stock diameter pipe, connects to EX7-423 center muffler)


1975-1978 49-State models (without catalytic converter)

These Spiders came with a restrictive single outlet exhaust manifold.Even a stock engine will see gains from converting to the earlier type two outlet exhaust manifold with matching downpipe (EX5-474), or an exhaust header. We recommend our larger diameter center and rear mufflers.The stock downpipe is not available new.

1975-1978 California models with catalytic converter

These Spiders have a catalytic converter under the passenger seat.The stock downpipe is available new (EX5-478), but no performance options are available for this system as it runs much further to the right (under the passenger seat) than the non-converter system. If it is suspected that the converter is plugged, a test pipe is available to replace it for testing purposes.Some customers in non-emission controlled areas have swapped the entire system from a non-California Spider.

The 1979 49-state models have a two outlet exhaust manifold which are fine for stock engines.The 1979 California models and all 1980 carbureted models had a single outlet exhaust manifold which is quite restrictive.Our exhaust header will restore performance lost from a restrictive stock manifold.If it is suspected that the converter is plugged, a test pipe is available to replace it for testing purposes.
