Most people modify the exhaust pipe from the middle, the tail section, the common method has a thick pipe diameter, reduce the muffler, etc., we must be in the modification exhaust, according to the characteristics of the car to confirm the effect they want, otherwise the loss of low torque do not say, afraid of even high speed horsepower are not accumulated up.

Friends need to know is the shorter the exhaust pipe is good at high horsepower and back down, slender shape of exhaust pipe at low torque and back pressure is high, the principle is the exhaust pipe of the short low velocity is slow, when high speed exhaust was clear, thin and high pressure, low and middle speed discharge waste gas will be very quickly, but high speed may be blocked.

Long tailpipes should be selected for road driving and shorter ones for racing.

Additional judgment consistent exhaust performance is good or bad, can to judge from the her voice, the first condition to hear the voice is stuffy inside, but it also can’t on behalf of the sound is good, if the loud sounds very empty, must have been back pressure is too small, powerful exhaust pipe, the voices and sounds full indirect means it can exhaust gas drainage of fast.

The smoothness of the exhaust pipe is related to the design of the first Catalytic Converter, the thickness of the middle pipe diameter and the size of the muffler. In particular, the modified Catalytic Converter with good performance can reduce the pollution value of the exhaust gas before it is discharged from the engine, and the oil-supply ignition system can cooperate with the air intake accurately in all aspects.

Many people may have modified their exhaust pipes just to listen to its beautiful sound.Don’t know you ever think, modified exhaust is can increase power, especially for turbocharged cars now run all the time, Catalytic Converter, modified exhaust is very good method, but the catalysts on the market at present although sort is various, but the quality is jagged, not completely at ease, but completely don’t have to worry about now.

Based on the advantages and disadvantages of the first section of the original factory, ZTEC has finally developed a Catalytic Converter with good effect or reputation for multiple brands and car systems after long-term research and practice. Welcome to consult.
