Want to improve the performance of your Cadillac Calais? Consider fitting it with a brand new performance exhaust system from CARiD. Cadillac customs exhaust systems are built to pull exhaust gases away from the engine, in this way eliminating the hindrance that prevents the engine from generating as much power as it is capable of. The stock exhaust restricts exhaust flow, only allowing a small amount of exhaust gases to make its way out of the engine at any given time. Spent gases stagnate within the engine, inhibiting the flow of fresh air and fuel needed for the generation of power. This lowers total power output. Replacing your stock exhaust system with a custom built one will eliminate this problem and push the engine to produce the maximum power possible.

There is plenty to choose from and you cannot go wrong with any of our brands because we only deal with the best the industry has to offer. From Borla to MagnaFlow, Flowmaster, Injen and Gibson, we have the power exhausts that will boost your horsepower by 10% or more. You can add an extra 40hp by combining the exhaust system with a performance header from the wide range available. Cadillac custom exhaust headers are specially engineered to boost exhaust scavenging and enhance the engine’s ability to breathe. Along with the power increase comes an increase in torque, which will allow you to enjoy greater towing power from your Cadillac Calais. There is also better fuel economy, thanks to the engine’s increased ability to burn fuel more efficiently. Because of its proven endurance and reliability, a custom Cadillac Calais exhaust system will save you lots of money in the long run.

    OPGI Exhaust Manifold
    This heavy duty cast iron 1974 Cadillac exhaust manifold was a perfect match for the original cracked one that had to be replaced. If one needs this part - it is perfect.
