2017 Fit 1.5AT currently installed KN high flow air grid and ABG in the tail section of the back pressure exhaust speed in the 3-4000 when the sound can but can only increase the throttle more than 4000 sound is not easy to hear and have to heat Car cold start when the sound is very difficult to listen to I want to change the tail when the low-turn when the sound of high and high when the sound high-pitched (but not the kind of feeling is a small car loaded a 200 pieces of exhaust and then in the row Trachea chisel a few holes on the noise) Some recommended I installed a genuine HKS tail section of some call me to add a turbine sound is obviously different I would like to ask under the domestic HKS straight with imported genuine HKS straight What is the difference between the sound and the performance of the sound is not only add the turbine kit does not change the exhaust sound will be different?
Exhaust system modification, said white, is to reduce the exhaust back pressure, back pressure definition, academic point is: because the exhaust pipe internal pressure, hinder the exhaust pulse force. Reduce the back pressure is actually so that the suction, exhaust alternately more smoothly, equal to extend the valve overlap time. Modified exhaust system, it should start from the end of the tail, this concept in the domestic refiners are aware, but what should be done, a lot of stores will take it for granted, or regardless of 3721, loud on the line. In fact, the modified (drum) to the tail (drum), the key to see the tubular design, and the design can be divided into "short thick", that is, to minimize the length of the body, and increase the diameter, Not suitable for daily traffic, because the back pressure is low, low in the low flow rate of waste gas, resulting in the cylinder mixture is not completely burned away, the low torque when the performance of natural difference, but to high turn, pulse-intensive, high Turn off the exhaust of the smooth, horsepower increase; the other on the Department
Do not know if the following information is useful to you. From the exhaust system can be modified car modification of the entry, almost 100% of the car mainly modified their own car, the first A time to think about to change almost all the exhaust system. But the knowledge of how many owners will go to ignore, may at this stage most of the modified exhaust system is for the shape, "throat, throat" exhaust sound running in the street is really very hot The
The exhaust system on the market, mostly refers to the tail drum, because the conversion of many people, and the price will not be too expensive, cheap a few hundred dollars have a transaction, but those products do not test data support, the actual use of the results to What is the point where no one really speak out, I believe that those who advertise on the hype can increase the number of the number of shops, so that he really get the data, the same is not. The market to buy the exhaust modified components can be divided into several categories: the first is the domestic production, such as in Hong Kong and moved to the domestic X Xun is one of the representatives, the price is not expensive, the first paragraph of the tail together Are all thousands of dollars level, the quality of the general but wins in the style and more, basically the domestic can buy the models they have a corresponding product, if you have opened a foreign models have been eliminated, such as JETTA and the flow, there are The However, the individual has not been used, it is difficult to estimate their design strength to what extent, but there are friends used to say that belongs to the middle level, of course, in the level of modified parts, the medium level must be better than the original.
