Q: Exhaust leak

asked by on February 09, 2016

I have an exhaust leak.

An exhaust leak can be caused by a few different things, one of which is simple wear and tear causing the system to thin out and break. If your motor mounts have excessive play the motor will move to much and put extra stress on your exhaust system causing premature wear and failures. An inspection should be performed by a qualified technician such as the ones here at YourMechanic to quickly and efficiently diagnose your concern.
