排气比赛用英语怎么说

排气比赛用英语叫做 "exhaust racing"。

它的来源源于汽车改装界，是指在汽车改装后改变排气系统，使得汽车排气声音更加响亮，并在比赛中进行评判。

下面是一些英文例句及其中文翻译：

"The exhaust racing team spent hours fine-tuning the sound of their car's exhaust." (排气比赛团队花了数小时调整他们汽车排气的声音。)
"The exhaust racing competition was intense, with cars revving their engines to produce the loudest sound." (排气比赛十分激烈，汽车主人们踩油门发出最响亮的声音。)
"The winner of the exhaust racing event had a custom exhaust system that produced a deep, powerful sound." (排气比赛的赢家有一个定制的排气系统，发出深沉而强大的声音。)
