Do You Find the Exhaust System of Your Car Annoying? 3 Signs It's Time to Replace the Muffler

The muffler reduces and redirects noise from the exhaust system of your car and also filters the exhaust gases from the car engine. Although the emission control system of your car is integrated into the catalytic converter, the condition of the muffler determines how the entire exhaust system functions. The muffler can last for about five to seven years, but you may replace it earlier if your car is frequently exposed to potholes, speed bumps and salt on the roads.
