Ford Mustang EcoBoost Downpipe, 2015+

Ford Mustang EcoBoost Downpipe, 2015+

Mishimoto continues to expand on our line of performance exhaust system components! After months of development and testing, Mishimoto has released the stainless steel downpipe for the Ford Mustang EcoBoost! This downpipe was designed with maximum exhaust flow in mind, using 3" mandrel-bent stainless steel tubing. This downpipe will easily outflow the stock restrictive piece, and allow your EcoBoost Mustang to make maximum power and torque! With this downpipe installed on our EBM Mustang and the ECU re-flashed with a more aggressive tune, the engine was able to make an additional 65whp and 108wtq over stock with our catted downpipe installed. With the Mishimoto catless downpipe installed, we produced additional gains of 9.8 whp and 8.3 wtq over the catted model, making this a great option for those seeking maximum power output. The Mishimoto downpipe was also designed to be easy to install, as well as adaptable to many exhaust configurations. We know there are many choices out there for cat-back exhausts, and the included 3.0"-2.25" adapter allows easy mating to the stock exhaust or most aftermarket cat-back exhausts with the stock-sized 2.25" mid-pipe. The adapter can also be omitted, so the downpipe has a 3.0" V-band outlet to mate...View more

The Composition and Functionality of an Automotive Exhaust System

When a car runs, it generates fumes due to the combustion of fuel. The exhaust is responsible for directing that gas away from the vehicle's passenger side. A car's exhaust is one of its critical components because it facilitates the optimal functioning of the engine. One must ensure that this system stays in good condition at all times, and that means replacing it when it fails.

Proper working exhaust systems are not just good for cars, but the environment as well. The gases released after combustion are toxic and must, therefore, be disposed of correctly. Exhaust pipes keep the air inside a car safe to breathe for the occupants. For this reason, a driver should learn how the exhaust accomplishes this and how to tell when something is not working right.

What it Entails

The automotive exhaust is made up of several linked pipes that provide a clear path for the combustion fumes. They run from the engine to the back of the car. These pipes are sized and shaped differently because each one is fitted on a section of the vehicle's underside.

Exhaust pipes also have to be designed around other parts that are located in the same section of the vehicle like the axles. Different car models and makes will have varying exhaust layouts due to the differences in their builds. The functionality remains the same, though.

A logical question when examining the exhaust pipes of a car is - why not have a single component rather than several pieces? For one, it simplifies the production process. If one pipe were to run from the engine bay to the back, then it would have to be bent at several points, which is tedious work.

It is more practical to have individual pieces that are already shaped appropriately. Another plus point of having multiple pipes is that a car owner can replace just one. If only part of the system is worn out like the oxygen sensor or catalytic converter, then it's more efficient to replace just that. Of course, you can get full exhaust systems in instances when a complete overhaul is necessary.

The Different Parts of an Exhaust

The first component of this system is the exhaust manifold, which is the pipe that links to the cylinder head and transports the fumes from the engine. Usually manufactured from cast metal, the exhaust head has openings that connect with the exhaust ports on the engine. It has flanges that wrap around the ports, forming a seal that keeps the gases from escaping. At the end of the manifold is a single opening where the fumes come out.

An oxygen sensor is integrated into the exhaust manifold or the exhaust pipe and is a standard feature in modern cars. Its role is to detect the level of oxygen contained in the exhaust. This information helps to calculate the amount of fuel required for a balanced air-fuel mix. The computer then adds or subtracts fuel accordingly, which promotes fuel economy.

As the fumes travel through the system, they pass through the catalytic converter, which is a pipe that resembles a muffler. It is responsible for converting the hydrocarbons and carbon monoxide in the fumes into CO2 and water with some converting nitrogen oxides as well. The degree of conversion depends on the type of converter. Catalytic converters are made with metals such as rhodium, platinum and palladium on the inside, so when the toxic gases pass through, they interact with them and become less harmful. A catalytic converter is an efficient approach to reducing environmental pollution.

The muffler, which is designed like a chamber, reduces combustion noises. The reaction from burning air and fuel causes explosions that can be deafening without a muffler. This part consists of several tubes and chambers that are laid out intricately. The design has to cancel out the noises while letting the fumes pass. A muffler has several layers of metal, including an insulated one to help absorb the loud sounds. The component takes a lot of pressure, which is why it has to be highly resistant to corrosion, shock and heat, among other environmental factors.

The final piece in the system is the exhaust pipe, which directs the gases out of the tailpipe at the end of the car's underside. Steel is a common choice for this component, but some carmakers use stainless steel. Corrosion is the biggest threat to the exhaust pipes, and that is why some car owners opt to have aluminised steel because it has a higher resistance to corrosive builds.

All of the systems are held together by flanges, gaskets, clamps and hangers. The pipes need fastenings to connect different pieces and hang the entire system from the underbody of the vehicle. Cars need fully functional exhaust systems to keep up with the required emission standards. Emission tests and extensive inspections are necessary to ensure that all systems are intact.
