Why Is My Exhaust So Loud? Causes and Fixes for Redding Drivers
Quiet a Loud Exhaust and Keep Fumes Out of the Cabin
A louder exhaust usually means a leak or a damaged part. Beyond the noise, a leak can let exhaust fumes into the car.
Louder than usual: book soon. Exhaust smell inside the car, or headaches while driving: drive with the windows down and come in now.
Why is my exhaust so loud? Usually because something in the exhaust system has cracked, rusted through, or come loose: a hole in the muffler or pipes, a leaking manifold gasket, a broken hanger or heat shield, or a damaged catalytic converter.
If your car suddenly sounds louder, rumbles at idle, or rattles underneath, something in the exhaust system has cracked, rusted through, or come loose.
