Most of the time, your engine is going to be at about 2,000RPM. You want an exhaust system that facilitates scavenging when the engine is going as fast as it can.Д«ut if youвЂ™re driving a vehicle on the street, your average RPM is going to range between 1,500 and 4,500 RPM. A large, unrestricted exhaust is a great idea when youвЂ™re trying to maximize top end performance. They do this because race cars spend most of their time driving around at high RPMs. When a race team gets their hands on a stock vehicle, the first thing theyвЂ™ll do is replace the factory exhaust with a bigger after-market system that doesnвЂ™t have a muffler. Likewise, an exhaust system tuned for 2,000RPM is going to be at least somewhat restrictive at higher RPMs.

As a result, an exhaust system that works well at 5,000RPM is going to be oversized for an engine at idle. At redline, your engine is producing a lot of hot exhaust gas. Therefore, you donвЂ™t want the exhaust gases to cool off too quickly OR stay hot for too long.Дў. As it becomes more dense, the velocity changes. As it travels thru the exhaust manifold, catalytic converter, and muffler, the gas cools. Most people tend to think of an exhaust system as a drain pipe вЂ“ the bigger the pipe, the more effective the drain. Racing Style Exhausts Are For Race Cars, Not Street Cars If theyвЂ™re traveling too quickly, the timing will be off and scavenging effects will be minimized.Д«asically, if you want to maximize scavenging вЂ“ and engine power вЂ“ your exhaust system has to be tuned to your engine. If theyвЂ™re moving too slowly, thereвЂ™s no vacuum effect. The problem is, scavenging only occurs when exhaust gases are traveling thru your exhaust system at the right speed. This ensures that the cylinder is emptied of exhaust and filled with clean air, leading to more efficient (and more powerful) combustion. At this point, scavenging acts like a vacuum pump вЂ“ a properly tuned exhaust system will pull the exhaust gases out of the cylinder. For a brief moment after the power stroke (but before the intake stroke), both the exhaust and intake valves are open. Scavenging occurs in the cylinders of your engine. This is because exhaust gases that are traveling in this speed range facilitate something called scavenging. Scavenging Is The Key To Maximizing Exhaust System PerformanceД®ngine exhaust gases need to maintain a certain minimum and maximum velocity as they travel thru the exhaust system. While a tuned after-market exhaust system will add power, a DIY system or straight pipe will most likely harm performance rather than help it. Unfortunately, thereвЂ™s quite a bit of misunderstanding about the way an exhaust system works. Usually, exhaust systems are pleasing to the ear and make driving that much more enjoyable. Provided you invest in a quality system, you donвЂ™t have to worry about any reliability or performance issues.

Exhaust upgrades are essentially risk free.

If youвЂ™ve already done an engine tune and an air intake, an exhaust is your next best вЂbang for the buckвЂ™ performance upgrade.

An exhaust upgrade is relatively cheap.While this gain usually isnвЂ™t вЂњbigвЂќ вЂ“ weвЂ™re talking about a 2-3% increase вЂ“ the modification offers a few benefits: But, what about an untuned system or a DIY exhaust system? LetвЂ™s find out.ДЄs stated in the intro, a correctly designed and tuned exhaust system can increase torque and horsepower across a wide range of the power band. One of the most popular vehicle performance add-ons is an upgraded exhaust system, and with good reason: A correctly designed and tuned exhaust system can add torque and horsepower across a wide RPM range.
