Modification of golf exhaust pipe

In order to have more sports visual effects, many users have modified the exhaust pipe. The improvement of the exhaust system is that the pressure in the exhaust pipe hinders the force of the exhaust pulse. Reducing back pressure actually makes the alternation of intake and exhaust smoother, which is equivalent to prolonging the overlapping time of valves.

Real air back pressure drum: comprehensively improve the torque and horsepower of the car. Made of SUS stainless steel, built-in vacuum back pressure valve can automatically adjust and control the back pressure in the drum, so that the back pressure generated by engine exhaust at different speeds can be balanced, thus achieving the purpose of improving power; That is, when the speed is low, the vacuum valve is closed, the engine has enough back pressure, and the engine starts quickly and climbs powerfully. With the increase of engine speed, the vacuum valve also opens. When the airflow passes through the drum, it immediately generates a tornado-like vacuum suction, effectively solving the vibration and noise caused by turbulence caused by uneven airflow, making the exhaust smooth and improving the medium and high speed power. It sounds at 1500 rpm and then mutes at 3000 rpm or higher. Deep voice, no * * *.

Domestic GTI still continues the overall appearance of the sixth generation golf, but GTI looks more sporty. The iconic honeycomb air intake grille and the logo of "GTI" on the right are very eye-catching, which can distinguish GTI from many cars at a glance. Headlights on both sides are the same as the golf high version, and the follow-up steering function is the same as the headlight cleaning function. Equipped with a more powerful engine, the air intake near the GTI front bumper has also increased, and the fog lights are closer to the sides of the car body, which is more murderous.
