There is a range of muffler types you can choose from with a cat back exhaust system with most people opting for a glasspack or straight-through muffler. Both of these options are designed to work well within the system to reduce back pressure. Deciding to purchase a performance exhaust system for your car is no easy task.
An upstream air injection point, ahead of the catalytic converter, is also sometimes present to provide additional oxygen only during the engine warm up period. This causes unburned fuel to ignite in the exhaust tract, thereby preventing it reaching the catalytic converter at all. This technique reduces the engine runtime needed for the catalytic converter to reach its "light-off" or operating temperature. Many vehicles have a close-coupled catalytic converter located near the engine's exhaust manifold. The converter heats up quickly, due to its exposure to the very hot exhaust gases, enabling it to reduce undesirable emissions during the engine warm-up period.

The amount of horsepower gained from installing a cat-back exhaust system varies by vehicle and the system’s design. However, when combined with other performance enhancements, the gains can be more significant. The primary goal of a cat-back exhaust is to reduce back pressure, allowing your engine to breathe better and operate more efficiently. The factory exhausts come in mandrel bent tubes made of stainless steel or aluminized steel. Besides offering longer durability, the construction also ensures there’s free flow of gases. To improve this, you can opt to replace some parts of the exhaust system using aftermarket performance exhaust systems.
