A center exhaust system may need to be replaced for a few reasons. The catalytic converter may be failing. Pipes may be corroded or clogged. Because the catalytic converter is tasked with converting the harmful emissions of carbon monoxide, hydrocarbons, and nitrogen oxide into less harmful elements like oxygen, nitrogen, water vapor, and carbon dioxide, a clogged catalytic converter may mean that these harmful and deadly gases are being released into the cabin of your vehicle. A clogged catalytic converter will result in a loss of vehicle acceleration, low gas mileage, and stalling. A completely clogged catalytic converter or exhaust pipes will cause exhaust backpressure and the failure of your vehicle’s engine. Routine center exhaust system inspections can prevent breakdowns and ensure proper exhaust system operating conditions. Being wary of the warning signs for impending center exhaust section issues can help you determine the proper time for replacements.
