An Exhaust System Secret for Florida Drivers

The Exhaust System Indicates Other Problems

We may be a shop full of auto-nerds, but the exhaust system can play a pretty cool role in helping you diagnose problems with your car. All you have to do is look at the smoke, specifically the color of it, coming from the exhaust’s tail pipe. The ASE-certified technicians at Christian Brothers Automotive New Tampa have compiled a couple of charts, depending on if you have a gasoline or diesel engine, to explain what the color of your exhaust might mean.
