If you thought that a bigger exhaust system meant more power, it’s not always true. Some drivers want an exhaust that will improve the sound and look of their vehicle. But, if your goal is to increase the performance of your vehicle, consider the points below:
It’s important to understand that the velocity at which your exhaust exits is one of the key elements to its performance. The idea behind upgrading typically comes down to increasing the exhaust piping diameter as well as increasing exhaust scavenging by aligning the exhaust pulses in a favorable fashion. When your engine is at low RPM, the amount of exhaust gases leaving is low, so the velocity it exits the muffler is low. You can increase this velocity by using a smaller pipe, but this creates a restriction for running at higher RPMs. Ultimately the goal of the exhaust system is to have the fastest exhaust velocity with the least amount of restriction. The whole idea is to increase the exhaust diameter as the amount of exhaust created by the engine increases. This reduces restriction and allows for more flow.
So, why should you upgrade, or not upgrade? If you are a daily driver with the average car, you will get better performance on the low end with the stock exhaust. However, if you have a dedicated car for speed, such as racing, it can make sense, to upgrade the exhaust. If you’re keeping the engine within the higher RPM range while driving, you’ll benefit from the lack of restriction the larger exhaust provides.
