Silicone vacuum tube

Silicone vacuum tube is designed for vacuum advance, windshield washer fluid, transmission modulator, and emission control. Available in sizes from BoreXWall 1/8”X5/64”, 5/32”X5/64”,  3/16”X3/32”,  1/4”X3/32”, 5/16”X1/8” to 3/8”X1/8”.

Silicone is resistant to hardening, cracking, ozone attack, sunlight, moisture, steam, dust, aging, various pressure ranges, and to many chemicals too. Additional advantages of Silicone are it is easier to install and run than ridged pipe, is not subject to corrosion, stress, or cracking, and it absorbs engine movement and vibration.

The automobile exhaust system

The automobile exhaust system is mainly used to discharge the exhaust gas from the engine operation, while reducing the exhaust gas pollution and noise. The automobile exhaust system is mainly used for light vehicles, minicars, buses, motorcycles and other motor vehicles.

Automobile exhaust system refers to the system that collects and emits exhaust gas, which is generally composed of exhaust manifold, exhaust pipe, catalytic converter, exhaust temperature sensor, automobile muffler and exhaust tailpipe.

Exhaust manifold

To start its journey the exhaust gas first passes through the exhaust manifold or if you have a performance exhaust, an exhaust header or extractor system. Performance exhaust systems are less restrictive and create a better exhaust flow to remove exhaust gas more quickly. This creates better engine performance resulting in an increase of engine power.

Exhaust Gas Recirculation (EGR)

Another unit you find on a diesel exhaust system is the Exhaust Gas Recirculation system or commonly called EGR. It is designed to decrease harmful Nitrogen Oxide (NOx) emissons and reduce the likely hood of detonation due to high combustion temperatures. The higher the combustion temperature the more NOx is produced. It cools some exhaust gas (using water) and bleeds the gas back into the intake manifold. This reduces the intake mix and cools the combustion temperature.

Diesel Particulate Filter (DPF)

A unit you find on diesel exhaust system is a Diesel Particulate Filter or commonly called DPF. This exhaust component is similar to a catalytic converter as it is needed to reduce exhaust emissions. It filters out particulate matter soot from the exhaust.

Why Should An Exhaust Be Upgraded?

When I looked into upgrading the exhaust on my car, my original goal was simply to see if it made any difference. Would performance increase or decrease? It’s important to understand that the velocity at which your exhaust exits is one of the key elements to its performance. When your engine is at low RPM, the amount of exhaust gases leaving is low, so the velocity it exits the exhaust is low. You can increase this velocity by using a smaller pipe, but this will create a restriction for higher RPM.

Exhaust scavenging makes an exhaust system more efficient because as your exhaust gases pulse out of the engine (from each exhaust stroke of the engine), you have a high pressure area leading the exhaust pulse, followed by a low pressure area (with a transition). This low pressure area helps to pull the next exhaust pulse out, meaning the piston has less work to do when it’s forcing out the exhaust gases. Ultimately the goal is to have the fastest exhaust velocity with the least amount of restriction (which of course isn’t as simple as writing that sentence).

The whole idea is to increase your exhaust diameter as the amount of exhaust your engine creates increases. This reduces restriction and allows for more flow. If you have modified your engine, you’ll need to modify the exhaust as well to allow for more airflow.

Exhaust systems, removing the gas

Shop exhaust systems

The exhaust system on your vehicle is an important part of the combustion process in your engine. The intake side mixes fresh air with usually petrol or diesel, feeds it into the combustion chamber in the cylinder head, where it is detonated (controlled explosion) and the exhaust system takes that residue gas flow and expels it out the back of the vehicle.

What does an exhaust system do?

Combustion produces noise and exhaust gas which is extremely hot and through a length of exhaust pipe and components, ducts it out the rear of the vehicle. There are a lot of component parts that make up the exhaust system and these can be purchased individually or as a set. Lets run through it from the front where it leaves the exhaust port on the cylinder head to exiting the rear of the vehicle via a chrome exhaust tip.
