Apr 28,  · A straight pipe system can sound better than performance exhaust systems, but performance systems come in many shapes and sizes. Chrome plating and fancy exhaust ends for your performance exhaust can be quite the improvement on your vehicle’s look. Usually, exhaust systems are pleasing to the ear and make driving that much more enjoyable. Unfortunately, there’s quite a bit of misunderstanding about the way an exhaust system works. 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. If you have a straight pipe exhaust equipped, then you have a pipe that starts from the header. It can provide you with more torque and horsepower with a racing engine, but it is usually only permitted on closed racing paths or circuits. Unless there are jurisdictional exceptions, you .

As stated in the intro, a correctly designed and tuned exhaust system can increase torque and horsepower across a wide range of the power band. 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.

Engine exhaust gases need to maintain a certain minimum and maximum velocity as they travel thru the exhaust system. This is because exhaust gases that are traveling in this speed range facilitate something called scavenging. Scavenging occurs in the cylinders of your engine. For a brief moment after the power stroke but before the intake stroke , both the exhaust and intake valves are open.

At this point, scavenging acts like a vacuum pump — a properly tuned exhaust system will pull the exhaust gases out of the cylinder. This ensures that the cylinder is emptied of exhaust and filled with clean air, leading to more efficient and more powerful combustion.

The problem is, scavenging only occurs when exhaust gases are traveling thru your exhaust system at the right speed. Basically, if you want to maximize scavenging — and engine power — your exhaust system has to be tuned to your engine. Most people tend to think of an exhaust system as a drain pipe — the bigger the pipe, the more effective the drain. This is incorrect for two reasons:. Exhaust is a heated gas. As it travels thru the exhaust manifold, catalytic converter, and muffler, the gas cools.

As the gas cools, it becomes more dense. As it becomes more dense, the velocity changes. Exhaust gas volume changes with RPM. At redline, your engine is producing a lot of hot exhaust gas. As a result, an exhaust system that works well at 5,RPM is going to be oversized for an engine at idle. They do this because race cars spend most of their time driving around at high RPMs.

You want an exhaust system that facilitates scavenging when the engine is going as fast as it can. Most of the time, your engine is going to be at about 2,RPM. Therefore, a race car style exhaust system is a bad upgrade for a street vehicle. Street cars need good performance at stop lights and on highway on-ramps. A straight pipe, for example, can cause exhaust gas velocity to increase. This will likely reduce engine performance below 2, or 2, RPM, making your vehicle a little slower to launch from a stoplight.

Automakers go to great lengths to tune the stock exhaust system in your vehicle. They choose a specific exhaust tube diameter for a reason, and they also set the distance between the manifold and the muffler for a reason.

While the OEM configuration can absolutely be improved upon, these improvements must be done by someone who understands exhaust gas velocity. Generally speaking, deleting a muffler increases exhaust system velocity. That will rob your engine of low-end torque.

In summary, your OEM exhaust system is better than you might think. While it can be improved upon, you need to be careful about how you modify it. Generally speaking:. It goes into the technical details that the original article only briefly touched on. Big thanks to Jason for this great story. I know I learned something today.

Skip to main content Skip to footer 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.

But, what about an untuned system or a DIY exhaust system? Exhaust upgrades are essentially risk free. The upgrade is fun to drive. Usually, exhaust systems are pleasing to the ear and make driving that much more enjoyable.

Scavenging Is The Key To Maximizing Exhaust System Performance Engine exhaust gases need to maintain a certain minimum and maximum velocity as they travel thru the exhaust system. This is incorrect for two reasons: 1. Street Cars Need Street-Tuned Exhaust Systems and Mufflers To recap: Exhaust systems are designed to facilitate scavenging Scavenging occurs when the exhaust gases maintain a specific velocity range Race-style exhaust systems are tuned to maximize scavenging at high RPMs, making them a bad choice for street cars Automakers go to great lengths to tune the stock exhaust system in your vehicle.

Generally speaking: You never want to delete or remove anything. Removing a muffler or catalytic converter can really screw up engine performance.

The cylinder head, exhaust manifold, and factory exhaust are a tuned system. Buy a tuned system if you can afford it. If you really want to delete your muffler, try replacing it with a straight thru muffler instead. Then you can decide if you need to delete the muffler or put the factory muffler back on. Understand the impact that tube sizing has on performance. This chart shows ideal exhaust tube diameters for various engine power levels. Good luck on your next exhaust upgrade!
