Do headers improve gas mileage?
While more involved from an installation standpoint, headers in combination with a cat-back system will give you a measurable boost in power. In most cases, fuel mileage will remain the same or improve a bit.
How to increase horsepower?
Upgrading to a performance cold air intake (CAI) system is one of the easiest and most affordable ways to increase horsepower. Here’s how it works: As air gets colder, it also gets denser. Your engine operates by taking in air, blending it with fuel and burning the mixture to produce power.
How does a large diameter throttle body affect horsepower?
Installing a large-diameter throttle body with bigger flaps allows more air to flow into the engine. Doing this increases several aspects of performance, one being—you guessed it—an increase in horsepower. And it’s no subtle shift. You’ll feel faster acceleration and a surge in engine power of up to 25hp.
Why do engines use cold air intakes?
Cold air intakes pull cool air in from outside of the engine. They are also designed to reduce air flow resistance and unwanted turbulence within the pipes, which ultimately reduce airflow into your engine.
Do high flow cats increase horsepower?
High-flow cats increase power across the full RPM range, but you’re going to notice the biggest boost of both torque and horsepower in the lower RPM range. Plus, you’ll be reducing the toxicity of your exhaust emissions while you’re at it. That’s a win-win in our book.
Why are exhaust manifolds thicker than headers?
To avoid the cracking issue, exhaust manifolds typically have to be made with thicker walls than the headers. This shrinks the space gases can travel through. Combine that with the compact size, and you get something of an exhaust bottleneck.
What does an exhaust header look like?
Visually, an exhaust header can look very similar to an exhaust manifold. Mostly because they both look like a collection of pipes. In fact, some vintage race car exhaust headers were called ‘bundles of snakes’ for that reason. However, there are a few differences between an exhaust header and an exhaust manifold.
Why are exhaust headers called bundles of snakes?
Mostly because they both look like a collection of pipes. In fact, some vintage race car exhaust headers were called ‘bundles of snakes’ for that reason. However, there are a few differences between an exhaust header and an exhaust manifold.
What is an exhaust manifold?
The exhaust manifold is the part attached directly to the engine, 1A Auto explains. It’s basically a block of metal with some small pipes attached to it. These pipes let exhaust gases leave the combustion chamber so the engine can keep running properly.
What is backpressure in exhaust?
It’s called ‘backpressure,’ WheelZine explains, and it prevents the combustion chamber from getting totally fresh air. Which means, over time, less horsepower and torque. Exhaust headers, though, with their longer individual tubes, are designed to prevent this.
Do OEMs have exhaust manifolds?
Instead, most OEMs fit their gasoline and diesel engines with exhaust manifolds. Your car’s exhaust isn’t just one long pipe. In addition to the muffler and catalytic converter, it’s comprised of a number of sub-sections. The exhaust manifold is the part attached directly to the engine, 1A Auto explains.
Why install aftermarket headers?
Horsepower and torque is the biggest benefit to installing aftermarket headers. Another benefit is the driver’s ability to open the car’s exhaust, which generates an appealing sound.
What type of headers give the most power?
Different style headers provide varying sounds and power. Long tube headers supply the most power and increase the vehicle’s sound. Mid-length headers give power ratios and sound qualities somewhat less than long tube headers.
What is exhaust header?
Exhaust headers are rarely found stock on vehicles; most vehicles have what is called a standard exhaust manifold. Headers decrease restrictions, therefore increasing horsepower and sound. Many varieties are offered such as short tube, mid-tube or mid-length, and long tube headers.
Can headers be installed by a mechanic?
It is recommended to have headers installed by a certified mechanic. Improper installation can result in exhaust leaks into the cabin of the vehicle resulting in potential carbon monoxide poisoning of the driver and passengers.
How to maximize horsepower?

Why did Zach Jobe install a new exhaust?
Arguably, the biggest reason why Jobe fitted a new car exhaust is to improve the Miata’s sound quality.
Why does a turbocharger need less back pressure?
It matters less for superchargers because they use the crankshaft to spool up, not exhaust gases. However, a less-restrictive car exhaust would still maximize the supercharger’s benefits. Other things to consider.
How much did Fenske pay for his exhaust?
Fenske paid $2500 for his S2000’s exhaust, and only added 3 hp. If the car was turbocharged, he might’ve gained more. But it is something to keep in mind if you’re thinking about upgrading your car’s exhaust. Aftermarket systems do add horsepower, but for naturally-aspirated cars, the improvements are fairly minimal.
What is performance exhaust?
Typically, though, the term ‘performance exhaust’ refers to the section that contains the ‘cat’ and the muffler. That’s why some aftermarket exhausts are called ‘cat-back’ exhausts, AutoAnything explains: because they replace the piping after the catalytic converter.
Why does exhaust gas spill back into the combustion chamber?
But if your car’s exhaust is too restrictive, the exhaust gases can spill back in due to back-pressure in the piping. This reduces available oxygen and decreases horsepower.
When will the airflow in a car be improved?
on July 1, 2020. Improving the airflow to a car’s engine is one of the first, and often easiest, modifications many enthusiasts make. Another common mod is giving your car an aftermarket performance exhaust. Many OEMs, such as Ford, GM, and Toyota, even offer them as factory accessories.
Do exhausts reduce back pressure?
The best performance exhausts, though, are designed not just to reduce back-pressure, but create partial vacuums, Road & Track explains. So not only are the exhaust gases flowing more quickly, they’re actually being sucked, or ‘scavenged,’ out.
