Corvette Central offers exhaust systems and parts for all eight generations for the Chevrolet Corvette. Here’s a timeline showing the Corvette’s exhaust details as it evolved over 70 years.
It’s mentioned that change is inevitable, and the evolution of the exhaust programs on the Corvette is an ideal instance. For 70 years, via eight generations, the engineers have frequently superior the efficiency and sound, producing many choices to get you precisely what you need in your Corvette.is proud to supply one of the best programs to fulfill the altering types and efficiency choices it doesn’t matter what 12 months your Corvette is.
Talking of evolution, Corvette Central takes us via the evolution timeline of thebeginning with the C1 technology after which exhibiting the advances and choices obtainable via every technology till we attain the present-day C8s.
C1 Corvette – 1953-1962
The Corvette engineers initially supplied the 1953-1955 Blue Flame 6 straight six-cylinder engine, a twin exhaust that includes three cylinders per pipe.
The 1956-1962 fashions gained a V-8 engine and featured twin exhaust. A few of these got here with a crossover pipe. Two variations for the mufflers had been obtainable: quiet oval or spherical off-road. The pipes measured 7/8 inch.
C2 Corvette – 1963-1967
In 1963, pipes had been both 2.0 inches or 2.5 inches. 1963-1965 exhaust manifolds might be both 2.0 or 2.5-inch outlet measurement.
After 1965 all small block engines had 2.0 manifolds, though the upper horsepower engines continued to have 2.5-inch pipes, which had a smaller 2.0-inch connection to the manifold.
Massive block engines had 2.5-inch manifolds and pipes. 1963-1967 mufflers had been commonplace, or the optionally available N11 off-road mufflers, with one much less baffle inside, giving much less restriction and a extra aggressive sound.
Whatever the pipe measurement or engine horsepower, muffler retailers are all the time 2.0 inches.
The manufacturing unit supplied an optionally available aspect exhaust from 1965-1967 with 2-inch or 2.5-inch inlet pipes with aluminum covers—choice code N14.
C3 Corvette – 1968-1982
1968–1974 small block engines all had 2-inch manifolds, though the upper horsepower engines continued to have 2.5-inch pipes, which had a smaller 2-inch connection to the manifold.
Massive blocks continued with 2.5-inch pipes aside from 1969, which used 2.0-inch pipes.
1968 programs will be substituted if 2.5-inch pipes are desired. The optionally available N11 off-road mufflers had been additionally obtainable in 1968.
An optionally available aspect exhaust was supplied solely in 1969 from the manufacturing unit, 2” inlet pipes with diecast chrome-plated aluminum covers—choice code N14.
1975-1982 programs have Y pipes routing the exhaust via a single catalytic converter, then splitting to separate mufflers.
C4 Corvette – 1984-1996
The 2 into one into two, single catalytic converter routing scheme continued from 1984-1990.
The pipe measurement is 2.25-inches.
In 1991 true twin programs returned as GM began to put in a convertor connected to every manifold.
The pipe measurement elevated to 2.75-inches.
C5 Corvette – 1997-2004
Twin pipes with twin converters continued. A crossover was manufacturing unit put in.
Mufflers are mounted laterally behind the transaxle.
Pipes are 2.5-inches, aside from the Z06, which had 3.0-inch titanium pipes, which lowered the load by practically 50%.
C6 Corvette – 2005-2013
Much like the C5 with a brand new innovation, the Twin-Mode, NPP choice exhausts. This selection includes a vacuum-operated valve on the muffler outlet, which opens beneath full throttle. The result’s a extra aggressive sound and including 5 horsepower. Pipes are aluminized stainless-steel with a crossover and commonplace 3-inch polished ideas or 4-inch with NPP.
C7 Corvette – 2014-2019
The ECU-controlled NPP choice for exhaust continues to be supplied. Sound ranges had been managed primarily based on RPM and throttle.
Pipes are aluminized stainless-steel, and inventory contains 3-inch polished ideas. The NPP options the 4-inch model.
C8 Corvette – 2020-Current
3-inch stainless pipes meet at an X inside a big insulated housing.
The brand new mid-engine Corvette contains AFM – Energetic Gasoline Administration. In greater gears, the PCM deactivates cylinders, and the engine operates as a V4.
The muffler meeting features a pair of AFM valves and actuators on the muffler inlets immediately after the Catalytic converters. They serve to limit the move of exhaust in V4 mode to keep up the rate of the move.
