I didn’t realize that decelerating while in gear makes this embarrassing farting sound, or is it just me? Much more prominent when you have cars on your surroundings where the sound would bounce off of.

  • I've noticed the same thing. That's just how the motor sounds. I only have the cat back.

  • If a sound can embarrass you, you should not put aftermarket exhaust on your cars.

    Many people pay many dollars for that sound
