Mufflers & Exhaust
The exhaust system is an essential component of your motor vehicle. Firstly, the exhaust helps to direct noxious gases away from the cabin, so you will not be exposed to gases that can harm your immediate and long term health.
Another important function of the exhaust is to make sure your car is being as fuel efficient as possible, by monitoring the levels of oxygen emitted and using this information to balance the fuel/air mix of the engine to the optimum level.
Reasons for Exhaust Failure
Your vehicles exhaust system is located beneath a motor vehicle and is subject to damage from stones, dirt, water and other road hazards.
Internally extreme temperature changes together with a mixture of combustion gases and moisture, cause formation of acids that eat into internal metal surfaces. This corrosion is evident in the form of rust pin holes or cracks.
Warning Signs of a Faulty Exhaust System or Muffler
- When your vehicle makes a louder noise than usual.
- When fuel consumption increases or lack of performance is noted.
- When rust is visible on exhaust system parts.
- When rattles are evident from the exhaust system.
- When holes and cracks appear and exhaust gases leak.
- Danger Signs You Should Look Out For
When the smell of fuel or oil odours no matter how slight, are detected within the passenger compartment. The system could be leaking and lethal carbon monoxide levels building up.
Reasons for Maintaining Exhausts
Your exhaust system performs several extremely important jobs. It takes exhaust gases from the engine to the rear of the vehicle, keeping dangerous fumes away from the occupants.
It also keeps engine noise to comfortable levels inside and outside the vehicle.
Exhaust systems are made up of a variety of components, custom designed to fit individual vehicles using pipes and mufflers which maintain correct back pressure. This in turn enables optimum engine power with minimum fuel consumption.
The Single Biggest Cause of Exhaust System Failure
Rust is the biggest cause and it usually works from the inside out. A mixture of water and sulphuric acid in exhaust gases, corrode pipes and the internal baffling of the muffler barrel.
Vehicles used for short journeys, tend to corrode their exhaust systems more quickly. In this case, the muffler does not reach high enough temperatures to ‘dry out’, leaving the water and acid to accelerate the rusting process.
