General Tips on Buying an Exhaust System

Consumers can improve the likelihood of purchasing a suitable exhaust system for a Vauxhall Vectra by following a few general tips that apply to buying an exhaust system for any vehicle. Learning why an exhaust system is important to engine performance, understanding the roles of exhaust system parts, and learning about different exhaust system styles can help consumers in their buying decisions. Also, understanding the benefits and drawbacks of systems from the original equipment manufacturer and aftermarket exhaust systems is beneficial in making the right choice for an exhaust system.

1. Learn Why an Exhaust System Is Important to Engine Performance

To achieve its full performance potential, a car engine relies heavily on its exhaust system. Compressing air and fuel in the engine's cylinders results in combustion. This reaction leaves behind dirty air fumes, which the exhaust system removes so that fresh air can enter the engine for a new combustion cycle. The fumes have much less oxygen than fresh air does, so leaving them behind in the engine cylinders results in weaker combustion on the next cycle.

Combustion also creates heat. Hot air is less dense than cold air, therefore containing less oxygen when the volume of air is equal. Removing hot air from the engine cylinders keeps the incoming fresh air cooler, resulting in more oxygen in the cylinders and stronger combustion. The exhaust system's ability to keep hot, dirty air out of the engine therefore helps an engine achieve its full potential for power.

2. Understand the Roles of Exhaust System Parts

Exhaust problems may be related to one of the parts in the system, so consumers should see if they can resolve exhaust issues by replacing a single part before buying a whole new exhaust system for a Vauxhall Vectra . The table below indicates the role of the primary parts in an exhaust system.




Takes air from engine cylinder; number of manifold heads equals number of engine cylinders; merges into single pipe on opposite end of heads

Catalytic Converter

Converts carbon monoxide and hydrocarbons from fumes into water vapour and carbon dioxide; reduces environmental impact of exhaust


Takes cleaner exhaust from catalytic converter and moves it towards end of exhaust system; mandrel bends and greater diameter reduce backpressure


Absorbs the sound that combustion creates and sends through the exhaust system; baffles or fibreglass-construction absorb sound


Pipe at end of exhaust system; expels cleaned engine fumes and muffled engine sound

The downpipe, silencer, and tailpipe combine to form the cat back component. One of the main purposes of the cat back is to reduce the pressure caused by expelling hot air from pushing back towards the engine. If too much pressure builds up, hot air comes back into the engine and reduces the power that combustion produces.

3. Learn About Different Exhaust System Styles

Exhaust systems may be single-exit or dual-exit. These styles refer to the cat back component. A single-exit cat back has one downpipe, one silencer, and one muffler. A dual-exit cat back has two of each of these parts. One does not necessarily perform better than the other, but they both can provide different looks for a Vauxhall Vectra. Whereas a single-exit system has the tailpipe below one side of the rear bumper, a dual-exit system has tailpipes at both ends of the bumper.

4. Understand the Benefits and Drawbacks of OEM and Aftermarket Exhaust Systems

The stock exhaust system that comes with a Vauxhall Vectra is of the original equipment manufacturer (OEM) designation. This means that an independent manufacturer made the exhaust system for the Vectra based on Vauxhall's specifications. Consumers can also buy aftermarket exhaust systems. This designation indicates that an independent manufacturer has produced the exhaust system based on its own designs.

An OEM exhaust system should perform the same as the stock system did. An OEM system is a solid choice for those who are not looking for an upgrade but want the exhaust on a Vectra to perform as it did before. An aftermarket exhaust system can result in enhanced performance. Producers of aftermarket exhaust systems for the Vectra often tinker with the specifications of the stock system to improve the Vectra's ability to rid itself of hot, dirty fumes. Consumers should be prepared to deal with side effects, such as decreased fuel-efficiency, to their vehicles with aftermarket exhaust systems.

Tips on Buying an Exhaust System Specifically for a Vauxhall Vectra

Following a few tips on buying an exhaust system specifically for a Vauxhall Vectra helps consumers avoid purchasing a system that cannot be used with the car. In order to avoid this, one should know how to find a compatible exhaust system for a Vectra and take measures to ensure that the new exhaust system keeps a Vectra street legal.

5. Find a Compatible Exhaust System for a Vauxhall Vectra

The key to finding a compatible exhaust system for a Vauxhall Vectra is to match the exhaust system to the Vectra's engine. This can be a bit tricky since not all Vectras have the same engine. First, Vauxhall has been producing the Vectra since 1988. Second, different Vectra trims from the same model year can have different engines. The Vectra has had a four-cylinder engine and a six-cylinder engine, so an exhaust system must have the right number of manifold heads in order to be compatible. Cylinder volume can vary from engine to engine, so an exhaust system must also be able to keep pace with the amount of air the cylinders displace. Sellers of exhaust systems should be able to provide compatibility information to help consumers avoid getting stuck with systems that do not fit their Vectras.

6. Ensure the Vauxhall Vectra Remains Street Legal

When fitting a new exhaust system, it is important to ensure that doing so keeps the Vectra street legal. The British government regulates vehicle emissions and noise production. OEM exhaust systems should keep a Vauxhall Vectra within the regulations, but an aftermarket system may alter the Vectra's exhaust in a way that makes the car illegal to drive. When it comes to emissions, consumers should make sure that the exhaust system's catalytic converter sufficiently reduces pollution. For noise, consumers should ensure that the silencer muffles enough engine noise. One can consult the local council for current regulations regarding vehicle emissions and noise.

How to Buy an Exhaust System for a Vauxhall Vectra on eBay
