The car began running very loud especially when started and whenever I hit the accelerator. The car is easily 2x louder than normal. It seems to drive okay, but I haven't taken it very far since the noise started. No check engine lights turned on.
What would cause my car to run very loud with no apparent warning? on 2003 Pontiac Vibe
Could be a problem with the exhaust or muffler. If you cant look at it yourself, give us a call and we will be happy to help you know whether it is something dangerous or not.
Cracked exhaust manifold?
