yesterday i was leaving a parking lot but there was a car blocking the exit sideways and wouldn’t move so i just went over the curb it was a steeper curb than i thought and my undercarriage smacked the concrete and now my car sounds like an old very loud lawn mower when i drive anyone know what i broke? 😭
You likely broke something in your exhaust system. You might have broken off a connection or punctured part of it.
Depending on where the puncture is it could impact your ability to pass a state safety/emissions inspection, could cause harmful gasses to accumulate under/inside the vehicle, could impact the vehicle’s performance/mileage, or could do nothing other than make annoying lawnmower sounds.
I would recommend having a trusted mechanic take a look underneath the car. It’s possible you caused other damage at the same time that just isn’t as noticeable to you and could be a future issue.
Also, stop driving over curbs. Look for a different exit or practice your breathing and counting to 10.
