What Is the Purpose of Straight Pipe Exhaust System?
All of them just make power due to the conflict between valves. A lot of factory exhaust manifolds only provide a basic exhaust route. The stock exhaust tends to be quite restrictive. The piping gets close to hot and the restrictive design creates a large restriction to the flow. It’s not designed for high-performance cars and may not offer the best performing result. Other than the physical design, steel pipe can get rusty over time and the oxygen converter can’t clean very hot exhaust gases.
The purpose of an exhaust system is to help your engine perform well by evacuating combustion gases at the best possible rate. Every exhaust system consists of a header pipe, manifolds, rear axle pipes, and tail pipes.
One of the biggest advantages of a performance exhaust manifold is better throttle response. You get better mileage as the engine can breathe easier. The engine produces a little bit lighter exhaust gas with a better pressure ratio for the turbocharger.
A stock exhaust system works well on cars with stock engines; however, it might be a little underpowered on the performance of a high-performance car. A straight pipe exhaust system has no baffles or knockouts. It creates back pressure, and that’s what makes the vehicle run fast with the turbo.
Pros and Cons of Straight Pipe Exhaust
There are some significant advantages and disadvantages to straight pipe exhaust systems. First, let’s begin by explaining why straight pipes are widely used in exhaust systems for both small and large vehicles, as well as more specialized applications, such as tractors, snowmobiles, marine motors, and motorcycles.
- It is often less expensive than other available designs.
- It is very lightweight and simple. The airflow path is direct and uncomplicated.
- It can last a very long time because it has relatively few moving parts.
- It is less prone to failure.
- It tends to be louder and with more hissing than other designs, which alerts people to the presence of the vehicle.
- It has a pleasing aesthetic design.
- It is tolerant of high heat, just like straight pipes in your vehicle.
Straight pipes are so widely used because they are relatively cheap, simple, and easy to install. However, they also have some significant drawbacks. As a matter of fact, the U.S. Environmental Protection Agency (EPA) considers straight pipes to be illegal.
The EPA has also developed and released regulations to discourage the use of straight pipes.
Additionally, the use of straight pipes is illegal in many cities and states. They are also prohibited on many vehicles.
Straight Pipe vs. Performance Exhausts Systems
When you’re trying to decide whether or not to get the straight pipe exhaust or a performance exhaust system, you’ve got to consider several aspects of the vehicle:
- The type of material your vehicle is made of
- The current level of engine modification
- Your needs
Once you decide if you are looking for more performance, a quieter environment, or both, you can start looking at exhaust systems that will suit your needs.
The straight pipe exhaust is the easiest to install – all you need to do is cut off the stock exhaust and screw on the new pipe. A performance exhaust, on the other hand, requires welding skills.
Don’t assume that the straight pipe is cheaper than the performance exhaust. The only reason it costs less is because it’s so simple to install.
Performance exhausts can be designed in different sizes to provide a variety of options for performance. Depending on the pipe diameter of the atmosphere, they can even be designed for a specific weight range.
Performance exhausts can also be designed to provide a pleasant sound, if that’s something that you prefer, and are known to be very sturdy.
Precision Muffler has placed itself at a mid-level position which means that they have chosen to go with their strong points rather than just price. In some cases, it does come out on top, but that is measured in a small degree since it is not the most affordable nor the most expensive option available.
The company jumped with the times by including certain features like gaskets and various mounting brackets which are not necessarily required, but are a blessing to any customer. Of course, the performance has been out there for decades, so there is no surprise that it is up to par.
If you are looking for a direct fit exhaust system which is quality tested and guaranteed, it is definitely worth a shot. In the end, it will bring you optimal performance, not only in power, but also in a lightweight muffler.
