On the Web today too many companies are interested in one thing only, SELLING YOU a Catalytic Converter….whether needed or not! Emission systems on todays vehicles are intricate and complex. Many times on a first inspection or code read the replacement of a catalytic converter may be indicated, but in reality another component of the emission system could possibly be causing the problem. If this is true replacing the converter is not going to fix the root problem and you could be faced with the reality of having replaced a part that was never needed in the first place.

Our philosophy has always been, why sell a converter if it is not going to solve the customers problem, it’s bad business and definitely makes for a very dissatisfied customer. Many times we can help you diagnose your vehicles problem just by asking a few questions, we then may be able to advise you whether a new converter will fix the problem or not. We will also tell you whether another issue might be evident or not, if the replacement of a converter is not indicated WE WILL TELL YOU THAT TOO! So if you have questions or would just like to speak with people who knows cats, give us a call, no problem is too small!
