In order to realize what advantages custom exhaust can provide as compared with the restrictive stock exhaust, let us itemized each exhaust component and see what benefits they can contribute once they are modified.
Increased in Horsepower
With custom exhaust, an increased in horsepower can be attained through the following:
Cat-back exhaust - unlike restrictive stock pipes, cat-back exhaust offer higher flowing units which product additional horsepower.
Headers or exhaust manifold – unlike with stock headers, custom exhaust manifold does not just focus on the flow of exhaust gases. It lessens backpressure since it allows quicker exit flow of gases. Faster exit flow of gases means faster burning of fuel.
Resonator – this car ad-on yields more horsepower without wasting much fuel.
Improved Engine Sound
Noise control is managed by two parts of exhaust which are mufflers and resonators.
Mufflers - Different areas with their own zoning regulations are mostly not favourable for the racers. They would be allowed provided the maximum level of 95 to 100 decibels is followed within 100 feet. With a modified muffler, one can go below those limits without, in any negative way, affecting the engine’s power.
Resonator – this is a tube or chamber that produces sound waves that negate the residual noise that muffler cannot. It is designed to produce destructive interference in the frequency range where the engine makes the most noise. Resonators, as part of custom exhaust, must only be installed by a car mechanic.
Catalytic converter – this device helps mufflers and resonators in controlling and cutting down exhaust noise. Unlike the resonator which cancels out noise, catalytic converter’s restricts the sound coming out of the exhaust pipe.
Increased Engine Performance
Mufflers – Modified mufflers are different from restrictive mufflers in such a way that they don’t create high pressure in the exhaust pipes. High pressure (or backpressure) in the exhaust path lessens the amount of burnt gases that can flow from the combustion chamber into the exhaust plumbing which leads to low engine performance. Custom-made mufflers minimize backpressure that allows a smoother flow of air and fuel into the combustion chambers thus increasing car’s performance.
Headers- similarly with mufflers, part of the custom exhaust is the modification of the car header. It permits quicker exit flow of exhaust gases.
Reduction of Pollutants
Catalytic converter – it converts toxic emissions (carbon monoxide, hydrocarbons, nitrogen compounds) into non-toxic substances thus reducing pollutants. With less pollutants, you are going to pass the emission test.
One obvious reason why car owner would want a custom exhaust is to have a high-performance and high powered car. Given the advantages above, it’s clear that several factors are involved. Of course, as the car owner, you can have your own designs but you cannot work alone. It would still be best to visit your trusted car mechanic to have the job done right!
