People often say that to evaluate whether a car is good or not, you can tell by listening to the exhaust sound. I believe that we can always hear the sound of sports cars on the road, the sound of the exhaust is very attractive to passers-by, the appearance also looks very personalized.
Nowadays, many family cars are also modified in the exhaust, so that the car's exhaust sound becomes bigger, the general family car by modifying the exhaust, the displacement of the whole car will also increase.
The role of the modified exhaust can be divided into three main categories, the first category is certainly to meet the aesthetic appearance; the second is to meet the auditory effect; the third is to reduce the exhaust back pressure, which is conducive to the performance of the vehicle at high speed.
In fact, I believe that more owners will spend their money on the first category, just on the exhaust tailpipe, although this modification does not improve the power of the whole car much.
But this location is one of the easiest for people to see. Some cars also for aesthetic reasons to cut off the original end of the car to install a shiny straight barrel gun barrel, and extend the show, giving people the feeling that it is like 1.5T power can instantly become 3.0T.
When you see some cars on the road with a lot of exhaust sound, but the acceleration ability does not match the sound, you know that the car only changed the exhaust end.
If you modify the mid-range, the power of the whole car will also be quite obvious, because there are three-way catalytic converter and muffler in the mid-range, after the modification, it will reduce the resistance of the incoming exhaust, which will enhance the vehicle's better power performance at high rpm.
If for some large displacement engine car, the replacement of the center section will give you a completely different experience.
Modification of this more is some partial power performance models such as ATSL, Civic, Fiesta, Golf, etc., that is, we say the civilian modification potential car. But this kind of modification will not talk about potential modification, more just enhance the sensory effect.
Because the headers are the part of the engine that is directly connected to the exhaust system, the effect of improving power output is still quite obvious if you make changes on the headers.
Changing the exhaust back pressure, brush ECU to improve performance, these are not professional play car people generally will rarely go to change. Must know a little tuning knowledge and professional tuning factory and also have excellent technology and funds.
More often than not, it is the most elementary and simple way to modify the exhaust tail section, as it does not affect the vehicle at all, and it does not cost much money to achieve the effect.
Although it does not change the sound, does not change the performance, and does not lead to substandard exhaust, but for some people may be a low investment, low risk and good return, the only feature is good-looking.
