What is the Catalytic Converter all about?

The catalytic converter is an emissions related component that is mounted in the exhaust pipe. Its purpose is to superheat unburned particles in the exhaust gases that are expelled from the engine. As the engine runs, the catalytic converter warms up to an operating temperature of 500-1200 °F. At this temperature the particles in the ‘dirty’ exhaust are burned and converted into water vapor and carbon dioxide. The catalyst inside is nearly always comprised of precious metals such as platinum, rhodium, or palladium. When the catalyst isn’t able to burn off the unburned hydrocarbons in the exhaust, an unpleasant odor can occur, a rough run or misfire may be felt, or the Check Engine light may illuminate.

Keep in mind:

Most cars will require the aftermarket Catalytic Converter to be welded to the exhaust pipes. Mobile mechanics can only do this service if you have a direct fit catalytic converter bought from a dealer.
When replacing the catalytic converter, it may be necessary to replace oxygen sensors as well.
Catalytic converter symptoms are often similar to other more straightforward issues. Get the Check Engine light diagnosed anytime it illuminates.

How it's done:

The vehicle is raised and supported on jack stands
The defective catalytic converter is removed
The new catalytic converter is installed and the vehicle is started to check for any leaks
The vehicle is lowered off the jack stands
The vehicle is road tested for proper operation

Our recommendation:

If you are consistently taking short trips with your vehicle, the catalytic converter may not be getting hot enough to completely burn away the hydrocarbons. To prevent the catalytic converter from getting clogged, take your vehicle for the occasional drive on the highway for 15 minutes. This allows the exhaust to sufficiently heat up and burn off any deposits in the catalytic converter.

What common symptoms indicate you may need to replace the Catalytic Converter?

Check engine light is on or flashing
Car has little or no power
Smell of rotten eggs inside the car or out of the exhaust
Poor fuel economy
Backfiring and rough running

How important is this service?

If the catalytic converter isn’t operating efficiently, the check engine light will come on and your engine can begin to lose performance. If the catalytic converter becomes plugged, the engine light will begin to flash and your engine may stall or no longer start. In extreme cases where the converter is plugged, the excess back pressure created can actually cause internal engine damage. If you are experiencing symptoms related to catalytic converter failure, get it checked soon.

BMW Z3 L4-1.9L - Car is making a noise - Hercules, California

Joshua is what you call a professional. You expect your mechanics to be an expert, and that's exactly what Joshua was. He was able to diagnose to problem, and make the necessary recommendations. He also went into detail regarding the background of my vehicle to explain why certain things are a certain way. Best of all, all of this happened at my house. Your Mechanic will be my go to service provider for vehicle service going forward.

BMW Z3 L6-2.5L - Expansion Valve (Orifice Tube) - San Antonio, Texas

Adam is extremely knowledgeable when it comes to A/C's. My car was previously taken to a different repair shop and misdiagnosed with needing a new compressor and after seeing the cost associated with this repair, we decided to wait to fix it. Adam ran a diagnostic on the A/C and determined the compressor was still functioning and we only needed a few parts replaced, saving us almost $1300! My car is comfortable again as the air is super cold and running well. Thanks to Adam, I actually look forward to driving my car again!
