Q : When does my car need a new exhaust system?
A: The lifespan of an exhaust system can vary. Most of today’s vehicles are made with high-quality steel exhausts, which will typically hold up for about five years, but there are many other conditions that factor in.
Q : Will a new exhaust system improve gas mileage?
A: In most cases, a new exhaust system will improve fuel efficiency. The question is by how much. Usually, it winds up being somewhere between 2 and 10 percent, which might realistically translate into two mpg.
Q : Can exhaust systems increase horsepower?
A: The great benefit of an exhaust system isn’t that it adds power, but that it allows you to use your current power more efficiently; thus, gas mileage is a better metric than horsepower. With that said, a new exhaust system can increase horsepower, sometimes by as much as 50.
Q : How does an exhaust system affect performance?
A: The exhaust system in your car helps provide you with a safe, reliable performance—reducing noise, reducing emissions, and more.
Q : What is a dual exhaust system?
A: Every vehicle has an exhaust system—either single or dual. The role of the exhaust system is to get rid of any excess gasses burned by the engine, helping the engine to stay cool and run smoothly.
Q : When does a muffler need to be replaced?
A: There are several telltale signs of muffler failure. The biggest and most obvious is that your car suddenly seems a lot louder than before—a pretty clear indicator that your muffler is no longer doing its job.
Q : Why is my muffler smoking?
A: A thin, vapor-like smoke coming from your exhaust pipes is nothing to worry about. Generally, that just means condensation has built up and is being burned off.
