Exhaust replacement

[Vcav82]

I am looking for direct fit OE replacement centre and rear muffler for a 1983 Pininfarina Spider. I found ANSA FA7245 and FA7247 on Rock Auto for a great price, however, they indicate that they fit 1979-1981 FIAT Spiders only. They seem to be identical to what is being offered from the FIAT parts retailers, although their mufflers are manufactured by IMASAF and are listed to fit 1980-1985 Spiders. Is there are reason the ANSAs only fit '79-81FIAT Spiders? The centre muffler looks like it has the correct 4 bolt flange. I also read online that some ANSA mufflers are actually manufactured by IMASAF in Italy. Wondering if this is the case with the Rock Auto mufflers. Anyone have experience with these particular mufflers?

Thanks,

Vince

All the OE center and rear exhausts for the fuel injected Spiders are the same, so anything listed for an 80 or 81 will also fit an '83 - '85. The rear exhaust for the '79 is the same as well, but as you know has a different flange on the center section for the converter.

The 79 and 80 carb machines have a 3-bolt flange to connect to to the catalytic converter. The FI cars have 4 bolt flances.

Called AP Emissions. They confirmed these ANSA mufflers are manufactured by IMASAF (same mufflers that are offered on the FIAT vendor sites).
