換死氣喉問題

This is a difficult question because it's subjective to judge if the exhaust sound is good or not. My feeling or definition toward a good exhaust sound may be different from yours. Also, even putting a same model of aftermarket exhaust on different models of cars will give you different sounds. This is very complicated issue.

By putting an exhaust system that has less restriction, the car will give up a little low end torque, so there's less power from the get-go, but then when you are in the mid to upper rpm range the car will actually gain more power and will be quicker. Some BMW and Porsche models have stock exhaust system that has a valve in one of the exhaust tips. In low RPM the valve is closed to generate more back pressure for better low-end torque, and will open itself for better flow (more power) in mid to upper RPM.

I don't know what your car is, but Fujitsubo has some exhaust systems that may meet your needs. There's a recirculation tube that can generate back pressure in low RPM for low end torque, route the air for better flow in higher RPM.

千奇唔好戍條換只換尾鼓架車ge聲靚D,對起步慢影响不大對尾段會有少訐幫助不是名牌一千樓下都有記住Ｎ組喉聲音會稍大

我諗你只有換架車至可以解決你咁高嘅要求同所有問題啦
