Exhaust systems are used not just in the automobile industry. In general, exhaust systems or pipes carry out gases away from a machine and its users. Imagine how indoor generators and furnaces can suffocate people if gases are not properly exhausted. This is the same rationale that is used behind vehicles exhaust systems.
Most car owners have no idea about how important exhaust systems are. In fact, most mechanics agree that the exhaust system is perhaps the most neglected auto part.
This, of course, is not right. Exhaust systems are like the excretory system of the human body. They get rid of the waste generated by the vehicles internal combustion engine. However, despite the importance of exhaust systems to vehicles, it is still not right to spend so much in one exhaust system. You may want to have a high performance exhaust, that is for sure. Nevertheless, mechanics guarantee that you can have the exhaust system that you need without fully emptying your pockets.
The first thing you need to know is that a performance exhaust system efficiently controls the exhaust and emission of your car. Thus being said, your exhaust system must have well functioning headers, smoothly bent and balance pipes, and free flowing mufflers (also known as silencers in other parts of the world). These parts are essential for an enhanced of performance your exhaust system.
If you want a custom made exhaust system, make sure that it is professionally designed in such a way that the performance exhaust will effectively draw the gas emissions out of the chamber. How does this happen? Professionally made exhaust systems uses the momentum of the gas travelling down the pipes to suck out whatever residual gas emissions are left in the combustion chamber. This means that the combustion chamber is not only cleared out, it also becomes open for more mixture during the chambers valve overlap phase. This creates a partial vacuum which in turn pulls in fresh charge into the combustion chamber whenever the intake valve opens itself.
Now if you want to build your own exhaust system, you are in for a lot of work. If it will be your first time, I suggest that you seek professional help. Online do-it-yourself instructional videos are no much for personal training one can receive through a professional mechanic. Most auto repair shops which offer exhaust system repair also offer other services such as customization and installation. Pretty sure, they will not mind teaching you a few things. Just make sure you clear up things first (e.g. professional fees).
Having an efficient professional exhaust system that works properly is the dream of any car owner. Fortunately, this is something that is not hard to achieve especially with the technology that auto repair shops have. Just keep in mind the things you exactly want to have and make sure you communicate those clearly with the mechanic.
