Components of Exhaust Systems

Before deciding what to do, it's important to understand the components of your exhaust system.

Headers:These are bolted directly on the engine and have four, six or eight ports, depending upon the whether the engine is a 4 cylinder, 6 cylinder, V6 or V8. Stock headers are normally cast iron and designed for low cost rather than efficiency.

Custom headershave equal-length pipes running from each cylinder before joining together; these improve engine efficiency by scavenging exhaust gases and give increased horse power and improved mpg.

Catalytic Converter:This is fitted downstream of the header and is used to neutralize noxious gases from the engine. It is a legal requirement, but most states permit its replacement with a custom cat provided the new unit meets or exceeds EPA requirements and is labeled as such (if not your car may fail its emission test). OEM cats are considerably more expensive than aftermarket units.

Downpipe:Some vehicles have a large bore pipe joining the header to the catalytic converter that often includes fittings for exhaust sensors. Some aftermarket downpipes incorporate the catalytic converter.

Resonator:The resonator reduces some of the harsher noises from 4 and 6 cylinder vehicles. Not all vehicles have resonators as they work in conjunction with the muffler to produce the desired exhaust note. It is fitted after the catalytic converter.

Exhaust Tubing:This tubing connects the components of the exhaust. The design of OEM tubing is restrictive with flow limiting bends caused by low cost manufacturing techniques.

Mufflers:These complete the process of reducing engine noise and create the desired note. OEM mufflers usually deaden engine noise to the extent that you can hardly hear the engine and they restrict performance.

Exhaust Tips:The only part of the exhaust you normally see are the tips protruding out the rear. They perform a critical function of ensuring that exhaust gases are not drawn into the vehicle. It's very common to replace these with better looking aftermarket tips.

Types of Custom Exhaust Systems Available

Although you can replace individual components, to improve performance and ensure that you have a good looking, long-lasting system, it's better to replace as much of the system as possible.

Turbo Back Exhaust:(for cars with turbo chargers) A turbo back system replaces all components downstream of the turbo charger.

Cat Back Exhaust:A cat back system replaces all the components downstream of the catalytic converter, and is recommended as an effective method to reduce exhaust gas restriction and produce a healthy exhaust sound.

Axle Back Exhaust:These replace the components after the rear axle, including piping, muffler and tips. It's cheaper, looks good but is not as efficient as a cat back exhaust.

Universal Mufflers:Universal mufflers are a cost effective method of replacing blown mufflers, can improve exhaust note and are cheaper.
