& Remote controller for adjustment of exhaust sound
In city driving or when you drive your car in your apartment, you'd better set the car in silent mode. Or you can let your car roar around street in loud mode.
But the point is, this Variable Exhaust system is expensive! Here in Korea, it depends on the tuning shop, the usual asking price starts from 1400$. Due to this high price, many potential consumers hesitate to pay on the products.
Considering these circumstances, new type of variable exhaust (original exhaust processed with variable valve) was released. Let's name it Original type variable exhaust. This original type variable exhaust is reasonably cheap.
Price range is about 450~500 USD.
This work is very simple. After making a hole on the middle exhaust pipe, weld a variable valve. It's all. But the problem of this type is discharging of exhaust emission under the car. that is likely to entail a increase in Flow around Exhaust Ducts of Flue Gas and I am sure no one wants to make him(her)self sick by breathing in emission.
This is improved type of Variable exhaust system. Instead of releasing pollutants under the car, this system discharge exhaust gas through the end muffler tip.
