Side pipes were not available on the new 1968 Corvette but were brought back for 1969 only. The side pipe setup was available through Chevrolet Parts Department for many years after 1969. But instead of bending towards the back of the car, the bends were directed towards the sides of the car.

These Patriot side pipes certainly provide more of that signature V-8 rumble that muscle car guys know and love, but it’s not unbearably loud. It’s certainly louder than stock, and you can hear it at a stoplight, as you cruise, and when you step on it, but it’s not so loud that you’d get pulled over for it.

The Chevrolet Corvette (C3) is a sports car that was produced from 1967 to 1982 by Chevrolet for the 1968 to 1982 model years. The C3 is the third generation of the Chevrolet Corvette, and marks the second time the Corvette would carry the Stingray name, though only for the 1969 – 1976 model years.

The name, Lake Pipes, is a reference to the area and play on words after the exhaust systems called lake pipes were used on hot rod vehicles in the 1940s and ’50s. Vehicles include hot rods, antique vehicles, muscle cars, late model and antique Corvettes and British sports cars.

Lake pipes The name is derived from their use on the vast, empty dry lake beds northeast of Los Angeles County, where engine specialists of yore custom crafted, interchanged and evaluated one-piece header manifolds of various mil thicknesses, a function of temperature, humidity, elevation and climate they anticipated.

The job of an exhaust system is to move burnt air-fuel mixture out of the engine. An exhaust system is also responsible to clean this emission and reduce unnecessary noise generated. This system also affects your cars overall performance so it actually matters how well designed it is.

The exhaust system collects the exhaust gases from the cylinders, removes harmful substances, reduces the level of noise and discharges the purified exhaust gases at a suitable point of the vehicle away from its occupants.

Because the exhaust gases exit each manifold through two pipes rather than just one, they can exit the engine faster and provide additional horsepower gains. Dual exhaust systems help reduce backpressure, which can save energy and increase the engine’s efficiency for better gas mileage.

Increased Gas Mileage: The engine in a dual exhaust vehicle runs more efficiently and with less effort. The more efficient the engine, the slower the rate at which the fuel burns, which means that you don’t have to use as much fuel as you would with a single exhaust system to go the same distance.

When your vehicle has dual mufflers, it will sound different and most people love the deeper tone that gives the impression of a more powerful vehicle.

Dual exhaust will give you a significant power increase because of the engine’s ability to breathe better. Thus, if you are trying to increase horsepower, dual exhaust may be worth the cost. You’ll have to replace the intake manifolds with headers, then add the proper piping, converters and mufflers.
