Not all drivers really understand the importance of having a good, high-flow exhaust system. The simple truth remains that a working exhaust system makes positive effects on an engine’s performance. That said, a bad/broken exhaust can also affect the car’s performance.

So, does a broken exhaust affect acceleration? Yes, it would affect acceleration because the exhaust works hand-in-hand with the engine to make a car move or accelerate. Well, there are quite a couple of issues a broken exhaust can cause, and they are explained below.

However, before we forge ahead, how do you know you have a broken exhaust? What are the signs you may get when your exhaust starts to fail?

Signs Of A Broken Exhaust Pipe

The moment you start noticing any of these symptoms, it’s time to check your exhaust pipe, and probably have it replaced.

1. Unusual Loud Exhaust Noise

When you start hearing loud unusual noise coming from the rear of your car, that could be your exhaust. A slightly broken exhaust pipe can cause such loud noises, and if the exhaust is blocked, you could hear such noises too.

2. Significant Decrease In Engine Performance

As hinted earlier, a faulty exhaust system would affect your engine’s performance. So, when you notice a drop in your engine’s performance and every other possible factor for such performance seem not to be the cause, it’s clearly a sign of a damaged exhaust pipe.

3. Hanging Pipe

If you find your exhaust pipe hanging or dragging as your drive, that’s because something has cracked inside, and it should be fixed as soon as possible.

Now that we have seen the possible signs that depict a failing exhaust, how does a bad exhaust pipe affect your car’s acceleration?

Does a Broken Exhaust Affect Acceleration?

Put simply, the answer is YES. A broken exhaust can affect acceleration due to loss of “back pressure.” Also, a broken exhaust will contribute to reducing fuel economy, as well as cause higher emissions.

These things happen because the exhaust system is designed to remove “water” emissions (fumes) coming from the engine. Hence, when the exhaust is unable to perform this function (due to a blockage or a broken part), the engine emissions won’t be removed efficiently.

Now, if the emissions are not removed, it affects the efficiency of the engine, leading to increased pressure, more fuel consumption, and possibly higher emissions.

Can You Drive With a Broken Exhaust?

Definitely, you can still drive your car with a broken exhaust; however, your car won’t deliver its best performance. More so, if the issue has lasted for a long time, you may experience misfiring as you drive, and of course, your engine’s fuel consumption will increase.

Again, depending on your location, you could be fined for driving with a bad exhaust, because it’d be making a hell of noise that would disturb other road users or even your neighbors. Though not advisable, it’s possible to drive with a broken or faulty exhaust.

What More?

Does a broken exhaust affect acceleration? Yes, it does, and it can result in costlier repairs if not fixed earlier. The exhaust system in every vehicle is directly connected to the engine for the purpose of removing emissions and waste fumes.

Hence, any issue with any component in the exhaust system can directly affect how your car engine performs. To change the exhaust is quite expensive, but it’s recommended you do that – especially if the exhaust pipe is also broken (not leaky).

You should let an experienced mechanic do the replacement as it is an advanced repair that requires professionalism.
