Effects. 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.
Do long tube headers make a car louder?
No. The header will improve the overall sound a little bit, but it won’t make it any louder.
What makes a truck sound louder?
There are 2 primary ways to make your truck louder. One way is to upgrade your factory exhaust system to an aftermarket unit that allows more free flow of exhaust fumes. You can also make your truck louder by upgrading the air intake system to a larger, less restrictive performance intake unit.
Are short tube or long tube headers louder?
As for drawbacks? Shorty headers aren’t as loud as long tube headers, although they’ll definitely have better sound than your stock manifold. You can choose unequal length headers for better sound, but equal length is the way to go for consistent gains in performance.Do headers make engine louder?
Installing an exhaust header can improve the sound of your car – but not so much. The engine could sound louder because an exhaust header is thinner. … Yes, it will slightly improve the sound. However, an exhaust header is designed to increase performance and not to increase the sound of your car!
What type of headers are best?
Full-length headers help produce more overall power with good power in the low- and mid-rpm ranges—right where most street-driven vehicles can use it the most! The longer primaries also reduce the chance of escaping gases getting drawn back into another pipe.
How much horsepower does long tube headers add?
Generally speaking a set of long tube headers on an American V8 can yield 20 to 30 HP without other modifications on vehicles with a stock exhaust system. Also headers generally require ECU retuning.
Are long tube headers worth it?
Another advantage with long-tube headers is that they not only give solid peak power numbers, but help to raise horsepower and torque in the low and mid-range of the RPM band, giving you more useable power down where you usually need it.Are headers worth the money?
The answer is yes, headers will boost performance – IF your vehicle is “prepared” for them. We discuss header types, their benefits, and conditions necessary for best results.
How much horsepower does long tube headers add to a 5.7 Hemi?The long-tube headers improved the peak power output from 407 horsepower to 434 horsepower, and the peak torque jumped up too, from 418 lb-ft to 439 lb-ft.
Article first time published onDo headers make a car faster?
However, headers alone won’t make your car much faster. You might pick up 2–4% more horsepower. Headers are a modification that is typically done to support other mods such as more aggressive cams, air intake, and engine tuning.
Which headers are better for torque?
Shorties are also an improvement over stock cast-iron exhaust manifolds because there isn’t the restriction experienced with iron castings. Shorty headers deliver better low-to-mid-range torque. Medium and long-tube headers allow an engine to make more horsepower at high rpm.
What can I put on my truck to make it louder?
- Headers. Instead of keeping the restrictive exhaust manifold your truck, swap that for a set of headers. …
- Mid-Pipes. Aftermarket mid-pipes make a far greater impact on your truck’s sound output. …
- Catbacks. …
- Air Intakes. …
- Forced Induction. …
- Sample Some Sounds.
How can I make my truck sound deeper?
Start the engine, and walk around the vehicle while someone revs it up, so you can hear how it sounds. If you want it a bit deeper, you can widen the cut to about a third of the pipe’s circumference. Additional cuts, spaced about four inches apart, will add depth and volume to the sound.
What is the loudest truck exhaust?

- Flowmaster Super 10. Flowmaster Super 10 is the second loudest muffler. …
- Flowmaster Super 44. Flowmaster Super 44 is the third loudest muffler. …
- Flowmaster Super 40. …
- Hooker Aero Chamber Muffler. …
- Flowmaster 50 Series Big Block Muffler.
What do long tube headers do?
For long tube headers, the exhaust pipes are much longer and merge farther out. Because of this, each design impacts back pressure in the exhaust system in a different way. Longer port pipes result in lower exhaust back pressure. This means improved oxygen intake and a boost in horsepower.
Are headers good for your car?
Headers are one of the easiest bolt-on accessories you can use to improve an engine’s performance. The goal of headers is to make it easier for the engine to push exhaust gases out of the cylinders. … During the exhaust stroke, a good way for an engine to lose power is through back pressure.
What's the difference between headers and exhaust manifold?
The difference between them is that an exhaust manifold is a solid cast iron structure across all cylinders while an exhaust header is made up of a series of individual steel tubes for each exhaust port, welded to meet at a collector to bring the exhaust gases down to a single pipe.
Do you need a tune for headers?
And for aftermarket headers, the answer is yes, you should tune your car when installing a new exhaust header. Major performance mods like a header can significantly alter important variables like air/fuel ratio. Tune is required to ensure you get the most out of the header without future problems.
How much torque do headers add?
We did the math and came up with a staggering average increase of 46 lb-ft of torque. That means that throughout the entire 4,000-rpm band from 2,600 to 6,600 rpm, the engine made 46 lb-ft of torque more with the headers at every single data point.
Do headers increase mpg?
Exhaust headers are lighter. It is proven that exhaust headers which are tuned for economy, can improve the gas mileage by a small margin. And this is around 2-3 mpg improvement on the highway or city.
Can headers be too big?
Too large a header will reduce torque output of the engine and increase the possibility of exhaust gas reversion—again increasing heat. Simply put, torque is related to air velocity (the faster the air/fuel get through the engine), and horsepower to the volume of air/fuel that processes through the engine.
What size headers should I get?

Are stainless steel headers any good?
In terms of durability and corrosion resistance, stainless wins over mild-steel headers that are coated only externally with ceramic. Headers coated inside and out with ceramic should last just this side of forever, or at least comparable to stainless.

Are headers illegal?
Headers aren’t always illegal, some vehicles come stock with them and most short tube headers are considered legal in most states. … Not only will they make your vehicle louder, but it is also considered tampering with your vehicles emissions, which according to the EPA is illegal under federal law.
Are headers hard to install?
The fact is, today it’s usually cheaper to run headers than the stock manifolds! But nobody wants to hack their Mopar’s fenderwells, or worry about bottoming out and mangling the headers, or constantly fix leaks. Plus, headers are notoriously difficult to install, especially on Mopars.
Do you need a tune for headers 5.7 Hemi?
require a custom tune. Other modifications (e.g. CAI, high-flow exhaust, shorty header, etc …) can run with a factory tune but will benefit from a custom tune. The 5.7L Hemi PCM (powertrain control module) uses a Speed Density System (SPD), rather than a MAF (mass air flow) system, for engine management.
Are aftermarket headers better than stock?
Differences Between Stock and Performance Headers A stock car does not have headers. … An aftermarket stock header deals with the exhaust gasses in a much more efficient way, which improves the overall performance of your engine.
How much HP will a tune add to a 5.7 Hemi?
On a stock 5.7 HEMI you may only see gains around 5-10 horsepower. With other mods like an intake, headers, etc. the tune alone may see gains closer to 15-20 horsepower. Torque gains can be similar and you’ll likely notice better throttle and engine response.
What does upgrading your headers do?
While it may not make a drastic difference such as installing a turbo or supercharger, investing in high-performance headers can increase the engine’s torque, and subsequently the car’s horsepower. Depending on the type of car you have and exhaust system, upgrading the headers can result in a 5% increase in horsepower.
