Experiencing some problem with your catalytic converters? Then you might be needing a change now. So shift loyalty to Catco Catalytic Converters and you'll never need another replacement in your lifetime. If you start to hear some noise in your car's engine, then your oxygen sensor might be starting to be defective that later on causes failure to your catalytic converters. Improper management to your car's regular tune up can put your catalytic converters to a total wreck.Catalytic converters become defective when clogged, poisoned, or physically damaged. A good sign of a bad catalytic converter will be a sudden decrease in performance and a noticeable decrease in fuel economy. A clogged catalytic converter traps exhaust gas in front of the catalyst, which then creates back-pressure that prevents your engine from breathing properly. Your engine may also suddenly quit after a few minutes of driving with an increased back-pressure. It makes the engine feel like it is starving for fuel. Another sure sign that your catalytic converter is bad is when you can hear rattling noises emitting from the catalyst. Sometimes you may actually hear a whistling sound when the throttle is applied indicating a restricted exhaust flow or catalytic converter problem. This rattling may also be noticed more when the car is not doing anything while the engine is running.The Catco Catalytic Converters are manufactured in a state-of-the-art facility with exacting specifications.
