The sound is low, and the horsepower at high speed will not be sacrificed at about 90 decibels, and the formation of the three wastes will be mainly extended to achieve the effect of power improvement. (Cons:.)
There is a resonant sound at high revs, and there is not much improvement in horsepower at high rpm), and the S drum is used in engines with the following displacements. It is a high-performance exhaust pipe with a very good price-performance ratio. The sound is about 90 decibels, which improves the torque at medium and low speeds, starts fast, climbs strongly, and has resonant sound at high speeds.
The internal backpressure --- specially designed according to the characteristics of the car. Improve the torque at medium and low speeds, and the sound is not noisy. No resonance sound.
At high speeds, there is no resonant sound, and the acceleration is fast. (The sound is similar to the S drum, some models cannot be equipped with the S drum, only the internal back pressure.) The sound is about 90 decibels, which increases the torque of high and low speeds.
M drum --- variable back pressure design, according to the speed to adjust the size of the back pressure, at high speed there is no resonance sound, when the engine is at low speed, the gas flow speed is slow, the speed through the regulating valve will be slow, the vacuum is small, the suction force is small, and the exhaust gas back pressure stored in the unit time is large. When the engine is at high speed, the gas flow speed is fast, and the speed through the regulating valve will become faster, resulting in a large vacuum, more exhaust gases are discharged, and the exhaust gas at high speed is smooth. To achieve the effect of increasing torque and horsepower, the high speed is about 85 decibels, which is the most obvious and dynamic exhaust pipe in China according to foreign design concepts.
Sound characteristics: there is basically no sound at low speed, which is the same as the sound of the original exhaust pipe (but the torque increases); At 2500-3000 rpm, the sound comes out, with a muffled sound peculiar to sports cars, but not very loud; At 4000 rpm, the sound is quiet again, the same as the sound of a normal exhaust pipe.

Anonymous users2024-02-14I changed the exhaust pipe, changed it twice, and finally changed it back to the original factory, Shenma is all floating clouds, or the most powerful of the original factory.
The acceleration is powerful, and my brother advises you not to change it.
If you want to change it, don't make abg, and if you improve it, you will know the gap.

Anonymous users2024-02-12Hello, let's put it this way, do you modify the exhaust pipe or change the accessories? The quality of the accessories is average and sufficient! There are a lot of good exhaust pipes when you use it! All kinds of brands have their own characteristics, mainly depending on the direction and purpose of the modification! Briefly introduce a few brands, all of which are of high quality!
1 Japan"Trusts"Trust is of good quality.
2 cgw shanghai hao li Chinese own high quality brand exhaust 3 Japan jic magic
4 akrapovic Slovenia exhaust brand, motorcycle exhaust industry big guy 5 aspec American brand, very unleashed tuning style 6 Japan"Laryngeal King"Fujitsubo quality is recognized worldwide (in no particular order).

Anonymous users2024-02-10ABG's ** is not bad, and the praise in the modification circle is not bad.
The CGW brand is quite famous, ** a bit high.
1. Samples should be recorded in the cost.
2. Of course, the agreement can't be done in the account, and there is no invoice. >>>More
1) Lhasa is located on the Qinghai-Tibet Plateau, with low latitude, high terrain, thin air, large daily temperature difference, strong solar radiation during the day, which promotes warming, and weak atmospheric inverse radiation at night, which promotes cooling. The annual range is small, in summer, the high altitude makes the temperature low, and in the winter, the low latitude makes the sun not low. So the answer is c. >>>More
It's not that there's something wrong with the 360, it's that there's a problem with the operating system, and to be honest, I can't solve it, so I can only give you a general overview of what's wrong with your computer: >>>More
You are complaining about your husband while considering your own abilities, and in the situation you described, I suggest that you communicate first, and if you can't get a divorce. In this environment, children will not be good, and the friendly reminder of women's rights is not to complain about the ability of their partners, but about women's independence, and call on society not to underestimate women.
C Because CO reduces CuO, HCl and NaHCO3 form H2O, and the volume of water reacts with NaOH to become smaller, and it is possible that CO2 or N2 is generated when CO restores CuO.
