Exhaust system with resonators. For customers who wanted a quieter exhaust and, in some states, to conform to vehicle inspection standards for noise.

From an article by Dan Booth in the Avanti Magazine Issue 207.

Your Avanti is listed by the serial number. R2 R-2238 - (aardvark) - AOAI Forum - Nov 2023

You are the one that is confused by the two Red Avantis. You don't seem to know the difference between EX-2942 and the #8 Avanti. In the video it is plain to see the production Avanti with the Black interior is the #8 Avanti (63R-1014) and not EX-2942 with the Fawn interior.

Avanti Red used Black carpet only with the Fawn & Elk interior. There is no issue, the Avanti with the Black interior is not the Due Cento. In the film there are 2 Red Avantis, the Due Cento and #8 (63R-1014). The Due Cento can be seen with the door open and the Fawn door panel. Later a front end shot with the windshield being cleaned shows the lack of a hood ornament and non stock headlights and parking lights. A later shot shows the large mirror mounted on the dash. The other Avanti is the #8 car with hood ornament, stock lights, antenna, production dash with mirror on windshield and Fawn & Black interior.

Nelson is correct, the Due Cento was built with Fawn interior with black carpet. The shots of the interior are from the #8 Avanti and not the Due Cento. The interior shot also shows a finished dash with windshield mounted mirror which the Due Cento did not have.

That is an early quarter scale model. Here is another version.

If your parents were members of the AOAI they could be listed in an early AOAI Roster. Could you post the last name? Speculation from the above info. Don B & Kathleen Rearick 63R-1685

No need to contact Greg Cone. The answer is in the following link. https://aoai.org/forums/topic/4876-dry-r5/

This is from the SDC Forum on 1-2010. Richard Bennett posted this as part of a reply about the R5. The R5 engine on the Due Cento was a basic R3 engine with a Bendix Fuel Injection unit that sprayed the fuel into/through the dual superchargers and then into a custom built sheet metal intake manifold which fed into the intake ports of the heads. It ran a Gilmore pulley and belt system to eliminate belt slippage, a special grind camshaft (several different grinders made camshafts for it but nobody remembers which one was used), and a Shiefer magneto ignition. It did not run a dry sump system. The blowers ran the blower fluid through a reserviour and cooler in order to cool the fluid which was needed as they were producing about 20 lbs. of boost.

This is from an article by Richard Bennett. Bill Dredge was present at the Granatelli shop when the testing was done on the dyno and said that the engine, in his words, produced a whopping 638 HP. Quite an accomplishment for 1963! Driven by Joe and Andy Granatelli, the Due Cento reached speeds well over 200 mph according to the tach, but was not getting traction due to the wet salt and the best official run was 196.58 mph.

In this photo it appears the R5 has no dry sump.
