Automotive Exhaust System

Your vehicle exhaust system serves a variety of important purposes and does require regular maintenance in order to perform as well as it should. In addition to serving to remove the hot gases and fumes from the engine compartment that are the result of the internal combustion engine creating the power your vehicle needs, the exhaust system is also responsible for noise reduction and the control of harmful emissions. Repairs to the exhaust system can be expected to be required more frequently than repairs to or replacements of many of the other vehicle parts, because its position leaves it vulnerable to the potholes that are occasionally encountered along the busy roads and highways of the Houston TX area, as well as to the affects of road debris and the occasional driving mishap.

The exhaust system begins in the engine compartment with the exhaust manifold or the headers, depending on the type of exhaust system in use. This collects the fumes and gases resulting from the burning of the fuel, allowing them – and the heat that they carry – to be moved out of the engine compartment, down through the system as it passes under the vehicle and, after passing through emissions control devices and noise reduction processes and parts, out at the rear of the vehicle, via the tail pipe.

Made of sturdy metal, the average exhaust system will last quite a while, but due to the effects of time and the elements, it is not at all unusual to end up replacing the entire system, piece by piece, during the lifetime of the vehicle. Road splash and other moisture will eventually work its way into flaws in the surface caused by bouncing rocks and other debris that can be encountered on the roads and highways in and around the Houston TX region and allow corrosion to set in. Some people choose to replace the original exhaust system with a high performance exhaust system, which – in addition to lasting longer – can also help to improve fuel mileage. That's because high performance exhaust systems tend to have less bends, allowing the pathway that the exhaust travels to be less restrictive, requiring less engine energy, and thus less fuel, to be spent in pushing that exhaust through and out of the system.

Because of its position, the muffler tends to be the most frequently replaced part in the exhaust system. This part is responsible for noise reduction. In addition to muffling the sound, the muffler reduces noise with an ingenious inner design that bounces the sound waves around, allowing many of them to cancel each other out and eliminate their noise. In order to achieve that, is muffler is typically made of a thinner metal than other exhaust system parts, leaving it a bit more vulnerable to rust and damage from driving over rough terrain or curbs, as can happen every now and then when trying to fit into a tight parking spot on a busy Houston TX street.

Whether your vehicle has a standard or a high performance exhaust system, it can benefit from regular repair and maintenance. In addition to meeting the stricter emissions standards common to Houston TX and the rest of the nation, a well maintained exhaust system can save money on fuel costs.
