The Exhaust System

Pretoria Hyper Exhaust leader in the field of vehicle repairs, maintenance and servicing, will enlighten you about the exhaust system. You may (or may not) think that the exhaust is simply a piece of piping, but we can assure you, it is so much more than that. We will introduce you to the specific functioning of the exhaust, to the most commonly used exhaust system terminologies, to the different types of exhausts used on vehicles, and to how you can maintain your vehicle’s exhaust. 

Manifold or Header
In a common manifold, a single assembly shares all the cylinders that collects the exhaust gasses and then channels them into one pipe.
In the case of a header, each cylinder gets its own pipe that flows into one larger pipe, called the collector.

Header & Manifold
The header-back is the part from the outlet of the header to the final vent, that is, to the open end/back of your vehicle (the tailpipe).
We will discuss this system in broader details later.

The cat-back refers to the portion of the exhaust system from the outlet of the catalytic converter to the final vent, that is, to the open end/back of your vehicle (the tailpipe).
The cat-back system generally use a larger diameter pipe than your normal stock system. We will discuss this system in broader details later.

The turbo-back is the part from the outlet of a turbocharger to the final vent, that is, to the open end/back of your vehicle (the tailpipe).

Catalytic Converter
The catalytic converter, normally found between the exhaust manifold and the muffler, have the main purpose of reducing harmful emissions of hydrocarbons, carbon monoxide and nitrogen oxides that may escape into the atmosphere. 

Muffler (Silencer)
The muffler (also known as a silencer), controls the exhaust emissions and it quietens the engine down.
It looks like a large round or oval chamber (usually, but not always, found near the back of the vehicle) and it consist of resonating chambers covered by sound absorbing material. 

The tailpipe is the end of the final length of exhaust pipe where it vents (generally the only visible part of the exhaust system on a vehicle).
It often ends with just a straight or angled cut, but may include a fancy tip that is often of larger pipe diameter and mostly chromed.

Lake Pipes
Lake pipes refer to a set of exhaust side pipes; with these, your exhaust is routed from the manifolds along or beside the bottom of your vehicle’s body, beneath the doors.
They offer a performance boost as they have less backpressure than conventional exhausts.

Oxygen Sensor
In all modern fuel injected vehicles, there is an oxygen sensor mounted in the exhaust manifold or close to it in the exhaust pipe.
The purpose of the sensor is to measure how much oxygen is present in the exhaust.

Hangers & Brackets
Most exhaust systems are suspended from the underside of the vehicle and kept in place by a series of brackets and hangers.
More about these in the maintenance part of our discussion.
