I want to share my personal experience and the lesson I learned the hard way. Join me as I delve into the story of my regretful decision to delete the rear muffler of my beloved Z3 BMW.

Have you ever been tempted to make modifications to your car, thinking it would enhance its performance and give it an aggressive edge? Well, that's exactly what I thought when I decided to remove the rear muffler from my Z3 BMW. Little did I know, it would turn out to be a decision I would soon come to regret.
