If you’re looking to increase the performance and efficiency of your car above the stock specifications, installing an aftermarket exhaust system is the first thing you should consider. It’s a simple upgrade with a quick installation that can make a big difference! The more freely air can flow through your exhaust system, the more beneficial it will be for you engine. Aftermarket exhaust systems are built to increase the flow of air above that of your stock system.
The major differences between stock and aftermarket exhaust systems are in the construction of them. Stock exhaust systems are usually made using an inexpensive crush bend method, which leaves ridges in the exhaust pipes along the bends. These ridges create drag, which slows the flow of air. Stock exhaust systems are usually made out of mild steel, which breaks down over time and needs to be repaired or replaced periodically.
Aftermarket exhaust systems are built to reduce drag by incorporating a mandrel bend design, which remains smooth through the curves. Aftermarket exhaust systems are usually made from higher quality materials as well, like stainless steel or aluminized steel. This makes them resistant to rust and damage. Aftermarket exhaust systems are meant to last for a long time, often for the life of the vehicle. These systems are also equipped with expanded, wider pipes that basically draw the exhaust from the engine, creating cooler temperatures and greater efficiency.
How Does it Help?
Allowing the exhaust to flow out of your engine more quickly lets fresh air enter at a quicker pace. This increased air flow in turn increases fuel combustion, which amps up horsepower for greater performance. Because it takes less effort for exhaust to leave an engine through an aftermarket system, you will see an increase in your fuel economy as well. Your engine will be able to perform the same amount of work with less fuel.
Keeping hot air moving out of an engine helps to keep things cooler in there as well, which reduces wear and tear on the engine and allows for higher performance levels without overheating.
There are several different options available for those looking to upgrade their exhaust system, and which one you choose really comes down to personal choice. You may be looking for maximum performance, with little regard for fuel economy. You may be looking to save money at the gas pump, and aren’t too worried about your top speed. You may want to enjoy both of these benefits, and add a throaty growl to your acceleration as well. No matter what improvements you’re looking to make to your car’s performance, aftermarket exhaust is probably at least part of the solution.
