What is flex pipe?
Under the car, there are several common exhaust components that can fail. Many vehicles have what is referred to as a flex-pipe in the exhaust system. This pipe has a flexible metal interior, similar to an accordion, with a woven, stainless steel fabric around out. Over time, these flex-pipes fail and can leak.
How to tell if exhaust is leaking?
Here are common exhaust leak symptoms: When the exhaust of your car is leaking near the manifold, the efficiency of your vehicle could decrease by 3-4 mpg. This can happen because the leak bypasses the sensors that read incoming and outgoing oxygen. Thus, an excessive amount of fuel is burned.
How to fix a leaky exhaust pipe?
The first step in repairing an exhaust leak is identifying the source of the problem. Since the exhaust pipes get very hot, a best practice if trying to isolate a leak is to do it while the vehicle is cold. Never touch the exhaust system if you have been driving the car under operating temperature.
