Why dual exhaust

And if you have a dual exhaust system for your vehicle or want a vehicle that does have it , you may be wondering how exactly the dual system works. A dual exhaust system, which is typically on sporty cars or even added to a car so it appears more sporty, is distinguishable by two tailpipes on the rear bumper instead of only one tailpipe. Since an exhaust system controls and facilitates how fumes flow away from the engine, a dual exhaust system is beneficial because it removes the burnt gases from the engine and directs them out the tailpipes faster, which is better since it allows new air to enter the engine cylinders more quickly, which improves the combustion process.

It also improves the performance of the exhaust itself because there is more airflow with two pipes versus all of those fumes having to try to flow in one pipe.

If each bank has its own exhaust system, there is more space for more exhaust to exit the engine. For example, if your vehicle has eight cylinders and a single exhaust, all the used air is trying to get out one pipe, one catalytic converter and one muffler. This can cause back pressure — like a bottleneck traffic jam — thus robbing your vehicle of horsepower.

Adding a second exhaust system so that each head and exhaust manifold has its own system allows double the exhaust to be forced out of the engine, thus increasing horsepower. Dual exhaust also decreases some of the back pressure that is common with single exhaust systems. Another back pressure builder is the stock exhaust manifolds. Because of the way they are designed, they tend to increase back pressure. When you convert to dual exhaust, be sure to replace the manifolds with headers.

Choose headers that are stainless steel to reduce rust. Also, if possible, choose headers that are made so the pipe lengths are as close to the same length as possible. This further reduces back pressure and increases horsepower.

The faster those gases are removed, the faster new, fresh air can enter the engine cylinders and continue the combustion process. Most cars have a single pipeline that routes all the exiting fumes through a single channel. If a vehicle has a larger engine that produces more horsepower, it probably uses two channels to remove fumes from the engine quicker.

The more burnt gases that can be removed from the engine — and the faster they can exit — the better. Some vehicles accomplish this by having a single-channel exhaust with a wider pipe diameter, but other cars — especially those with low ground clearance — split the system into dual channels that let twice as much exhaust escape at once.

Just as a large group of people trying to leave a building through the same door can create a bottleneck or traffic jam, single exhaust systems can create back pressure which can rob your vehicle of horsepower and gas mileage. A true dual exhaust system provides each head and exhaust manifold with its own separate exit allowing double the amount of exhaust to be forced out of the engine. As a result, you will likely notice an increase in horsepower.
