Your an a hole. You modified your WRX so that it would backfire. You triggered my memories of my car accident by backfiring while passing me while coming from the other way.

Also your tune is stupid. Backfiring is not normal or efficient. Your fuel air is too rich and isn’t making you faster anyway.

It’s also highly annoying for everyone around you to have to hear a backfire all the time. My ears are still hurting like 15 minutes later and I had my windows up.

You make the rest of us car guys look bad. Get the tune fixed and stop being an a hole.
