Hi, I'm Bob Holcomb from Apex Automotive in Great Barrington, Massachusetts. Today, we're going to talk about why your exhaust would be whistling or making a whooshing noise, and the car will suffer from no acceleration. The most common cause is the car's catalytic converter. The engine would be mounted up here in front of this system. The rest of the exhaust is behind this system right here. If these catalytic converters melt, break, or in any way get deformed or damaged, they'll clog up in this pipe right here. The engine is a pump that pumps air into the system. If it can get through the exhaust system, you'll get a whooshing noise, where this car actually had that problem, and it was leaking out of this flex joint. You can see all the black in this. So, if you have a whistling noise in your car, and it doesn't appear to have good acceleration, there's a good chance that your catalytic converter has been damaged, and you shouldn't drive your car any further. And, these are a couple of quick tips about what to do if your car is experiencing a whistling or a whooshing noise and poor acceleration.
