1974 Chevrolet Corvette Convertible — Numbers Matching L48 350 V8, Last Year for True Dual Exhaust

The 1974 Chevrolet Corvette holds a specific and well-understood place in C3 history, and collectors who know the model know exactly why this particular year matters. 1974 was the last year the Corvette left the factory with a true dual exhaust system — meaning two separate exhaust paths running from the headers all the way to the rear. Starting in 1975, federally mandated catalytic converters forced GM to route the exhaust through a single converter under the car, eliminating the true dual setup entirely. If you want a C3 Corvette with that factory-correct dual exhaust configuration and no emissions equipment restricting the flow, 1974 is your last opportunity.

There is more to the 1974 model year than just the exhaust. The rear end of the car was redesigned for 1974 with a new body-colored urethane rear bumper cover that replaced the chrome bumpers used in prior years. That rear bumper design was used only for 1974 — the 1973 front end had already transitioned to urethane, but the rear was still chrome. In 1975 the design changed again. So the combination of the 1973-style front and the 1974-only rear makes this specific body configuration a single-year design. That is a detail serious Corvette collectors track carefully.

Chevrolet built 37,502 Corvettes for the 1974 model year, with convertibles accounting for 5,474 of that total. Convertible production was already declining — 1975 would be the last year for a Corvette ragtop until the body style returned for 1986. This particular car is a genuine survivor with 76,411 miles on the odometer, a numbers matching L48 350 V8, and a long list of correct factory and period-appropriate options.
