Hi JRV (et al!)

Wondering if anyone knows, offhand, proper size for the "donut" exhaust gaskets for US 328 (always love to have parts *prior* to disassembly!). My parts manual shows one between front header & connector, another between rear header & connector, and one on either side of the convertor.
Is this a NAPA-available part? Any reccomendations on lubricant (anti-seize) on flanges? And replacing hardware - grade 8 metric bolts or stainless (fracture risk?)?

Of course thanks everyone in advance. Merry Christmas!

Hi Carl,

Hi Carl,

Generally the donuts can be re-used without leaks. If for some reason they become damaged and must be replaced I acquire new ones from a Ferrari specific parts supplier such as AW Car Parts or GT Car Parts, or Algar. I am not aware of an American/NAPA replacement in the correct size, but maybe others know something.

Happy Holidays, JRV

Thanks JRV. If I get adventurous I'll pull exhaust and try to match up. From pictures on sodacomms website appear to be relatively common round tapered.

Thanks once again,

Carl

Are these the two I'd need (2 of each) for the US 328 exhaust?

Thanks,

I searched in vain all over Vegas for a day for the donuts went to custom muffler shops, Midas, etc, they are a overly large size and unavail except thru Ferrari parts
resellers the same with the bolts as the nuts have a small cut in them to lock on the threads.

You can reuse the donuts if you put some high temp RTV on them, they will seal fine

Just went out & ran down t

Just went out & ran down the two above-mentioned exhaust donuts today. Simepl donut is Carquest #F20223 and flanged is CQ# F7171. A bit less than factory at $3.40 & $7.12/ea respectively.

Measurements are:
F20223: ID 2.03" OD 2.40" height 0.435"
F7171: ID 1.785" OD 2.41" height (total) 0.660 (flange only) 0.230"
Apologies all measurements in English units my calipers are a bit older.

Pictures of each:

Mr. Ryerson do these match the factory ones you purchased?

PS Jealous of 930...when I was in 11th grade one of the senior guys' father bought him am 84 930...which he learned to drive a manual transmission on...

I only got to the cat gaskets, the 20223 looks like it but as I recall they were about 2.75" diameter, I could be wrong.

Funny I went to Carquest and Napa searched all catalogues they had nothing was big enough

Thought I'd give this thread some closure.

For the 328 I could *not* match factory gaskets with anything else & ultimately purchased factory. Expensive but glad I did.

Hope this helps someone in the future.
