Here are the basic differences between the single exhaust and the dual exhaust. You do not need professional degrees to understand it, trust me, my friend. And once you know it all, you do not need a professional anymore!
Single Exhaust System
In the single exhaust system, there is only one pipe that helps is guiding the burnt or exhaust gases out of your car or truck. If you are new to single exhaust, you should know that these come factory-equipped already. And in most vehicles, there are already added. In the case of a single exhaust, the vehicles usually have one manifold.
And in cases, the manifold can be two. It depends on the size of your engine. In the case of the four-cycle cylinders, there will be only one exhaust manifold. On the contrary, for the large V-6 engines, there will be two different exhaust manifolds. Each of these will be for each BANK or HEAD. You might be confused that if a truck or car that has two exhaust tips or two manifolds can settle for a single exhaust or not. For your information, yes, it can.
From the manifold, the pipes of the exhaust system will directly go to the catalytic converter and the muffler. For the single exhaust one, exactly before the catalytic converter and the muffler, the pipe that comes out of both of the manifolds will be combined in a Y.
And in easy words, a single exhaust will have only one and in the case of the dual exhaust, there will be two of each.

As we told before, the difference between the dual and the single exhaust system is the pipes. Yes, the dual one has two different existing points to do the same work but better!

This will be set before the converter so that it can control back the pressure and can easily develop horsepower. When there is a crossover between both exhaust pipes, it will create an H there.

These are expensive to buy and along with that, installing these will cost you extra too. Replacing these exhaust systems will also require a lot of money and effort. If you plan to get better service, you might like to pay! But another problem about this one is the lifespan of the dual exhaust.
