Exhaust Systems

What is an Exhaust System?

The exhaust system includes the exhaust pipe and the muffler. Without a muffler, what you would hear is the sound of thousands of small explosions coming out your tailpipe. A muffler dampens the sound. The exhaust system also includes a catalytic converter.

Standard exhausts compromise top-end power to reduce noise levels and ensure smooth power curves. Performance exhausts gain extra power by eliminating the compromise. Replacing standard baffled boxes with straight through silencers reduces restriction and increases power. Large bore pipe-work and modified manifold tract lengths are also used to maximise flow. There are many types of exhaust systems. Which you want and what your car needs may be different, so choose wisely.

If the engine is the heart of a car, then the exhaust system is either the nose or mouth. The stock exhaust system found in most cars and trucks is a source of great flow restriction. By replacing the exhaust system, you will discover a dramatic increase in power. Some of the more important parts in the exhaust system are muffler, exhaust pipe, and catalytic converter. I will explain these parts in the order that the exhaust gas passes through.

Dual exhaust system can help the engine breath more freely and thus dramatically increase the car's performance. This is done by have 2 converters that words parallel and each converters connects to its own muffler. Increased exhaust capacity may lead to extra horsepower from the engine by providing more efficient air flow within the vehicle from the beginning to the end

Your exhaust system is more than a muffler, it is a series of pipes that run under your car, connected with your muffler and your catalytic converter. The main function of your exhaust system is to control noise and to funnel exhaust fumes away from passengers. In some ways, a car's exhaust system works like a chimney on your house, directing the by-products from burning fuel away from the people inside.

A car's exhaust system routes waste gases from the engine to the rear of the car, where they are discharged into the atmosphere. Exhaust gases contain dangerous substances such as carbon monoxide, which can be hazardous if allowed to flow into the passenger housing of the car.

The exhaust system also converts pollutants into less harmful by-products, reduces the noise of the engine, and directs exhaust gases so they can be used to heat air and fuel before they go into the engine's cylinders to be burned. Finally, the exhaust system provides just the right amount of backpressure into the engine to improve its fuel-burning efficiency and increase performance. Key components of your exhaust system include: Exhaust pipes: Designed specifically for each car model to properly route exhaust to the back of the car Exhaust manifold: (Some engines have two), acts like a funnel, collecting exhaust gases from all cylinders and releasing it through a single opening.

Exhaust System Parts

Catalytic converter: Designed to reduce the amount of harmful emissions products by transforming pollutants into water vapour and less harmful gases.

Muffler: A metal container with holes, baffles and chambers that muffles exhaust noise.

Resonator: which works with the muffler to reduce noise. Tail pipe: (Found at the back of the car), is designed to carry exhaust gases away from the vehicle.

All components of the exhaust system are connected with a series of clamps, hangers, flanges and gaskets.

If you're looking for more performance from your vehicle, the two easiest components to upgrade are the air filter and the exhaust system. At the other end of the engine, your vehicle's stock exhaust system typically expels exhaust gasses according to standards of economy, sound, durability, performance and appearance, pretty much in that order of importance. In other words, stock systems are built inexpensively, give little or no exhaust note, should last for the length of the car's warranty, don't enhance performance, and pay little or no attention to appearance. That's perfect, if it's what you want.

A performance exhaust system, however, takes care of the same requirements but with different priorities. Performance is at the top of the agenda, followed by appearance and sound, durability, and then economy. Performance exhaust systems come with a guarantee that likely outlasts the car.

On a performance exhaust system, you can expect the pipes to be of a larger diameter and mandrel bent. Mandrel bending is a process that retains the diameter of the pipe, even if it's been bent 90 degrees. The goal is almost a "straight-through" design that maximizes flow, permitting more air to enter and exit the motor.

Installation is often simple, as many manufacturers design their systems to use existing mounting points. I watched a local tuner swap a stock system for a Brullen Cat-Back system on an Audi A4 in about 20 minutes. Of course, some applications will require more time, especially if bolts break or parts have to be welded. If you're in the market for a performance exhaust system, there are a few things to keep in mind. Even though these systems utilize the factory catalytic converter, you should still check that the one you like is emissions compliant. They typically will be, as long as you don't remove the converter, or otherwise tamper with emissions equipment

So why not upgrade to a performance exhaust system today.
