Gallery – 2 images In order to test this, I opted for the Cobra Sport TP86-BLK non resonated cat-back exhaust system specifically designed for the F56 Mini Hatch Cooper S. Cobra Sport are a specialist exhaust system manufacturer based in Sheffield, UK that offer class-leading TIG welded, custom exhaust systems for a wide variety of both everyday and performance cars. A new, louder exhaust system can give off a placebo-effect of extra power. This could be down to the fact the owner is experiencing a different drive due to the increase in sound, but I was adamant that the engine seemed a tad more powerful. I just had to find out. Testing on the rolling road The guys at AmD Tuning in Essex kindly allowed me use of their rolling road. Now we must remember that most cars using the BMW 2.0-L Turbo ‘B48′ engine often run slightly overpowered anyway. For example, this one was producing 206 horsepower with 296Nm of torque as standard, where Mini state 192 hp and 280Nm. Horsepower saw a slight increase – bringing it close to 215hp (over 8 horses and almost 23 more than Mini’s stated output. Engine torque saw the biggest gain with an incredible 325Nm achieved thanks to the new exhaust’s improved airflow. This chunky figure is 29Nm of torque up from what the car was already producing and a whopping 45 from Mini’s stated number. In conclusion, a new sports exhaust system not only gives off a better tone, there’s also a very good chance of increased engine grunt. A new system promises a slight horsepower increase, but more importantly, more pulling power (torque). Plus, if you do decide to remap the ECU one day, the exhaust promises even more gains thanks to its improved airflow, giving the car more space to breathe.
How much horsepower does a sports exhaust add?
The Most You Can Gain is 2-5% – If you want to know how much power you can expect to gain from adding an exhaust system to your car, assume that your engine will get 2-5% more powerful. More specifically, large engines like a big 6.0L V8 typically see about a 2%-3% horsepower increase. Smaller engines, like a 1.8L 4-cylinder, typically see a 3-5% horsepower increase. 
HOWEVER, exhaust systems have a multiplying effect if you combine them with other add-ons. The exhaust system by itself won’t add a lot of power, but combined with an air intake and a performance chip or power programmer you could see a significant increase in performance, You’ll also see a slight increase in fuel economy (assuming you keep your foot out of it, of course).
What does a sport exhaust do?
Improved Fuel Economy – Performance exhaust systems help to maintain optimal air levels inside your vehicle’s engine. These optimal levels then reduce the need for your engine to consume extra fuel to compensate for dirty air levels. Some people note seeing increases in fuel economy of around 1-2 percent after installing a high performance exhaust system.
Does a good exhaust increase horsepower?
4. How much HP does a performance exhaust add? – Aftermarket exhausts usually have wider pipes and other features that improve airflow to enhance engine efficiency, but how do these improvements translate into horsepower? Unfortunately, there’s no simple answer to this question, as the results will vary between different car models, engine specifications, conditions and more.
What difference does a sports exhaust make?
Performance – A better flowing exhaust can help your car to generate more BHP, How quickly you can get the exhaust gasses out of the engine places a limit on how quickly you can get fresh air into the engine and thus how much power can be made. A better flowing exhaust always improves the power your engine can make.
Performance exhausts achieve this in several ways. Pipework diameter, exhaust layout, and reducing obstructions in the exhaust all play their part. On a non-turbo engine, it’s all about keeping the gas in the exhaust flowing quickly. The action of getting the exhaust gas out of the engine helps it draw in fresh air at certain parts of the rev range.
The quicker everything is flowing, the more benefit you get from this. On a turbo-car, the big priority is increasing the flow-rate of the exhaust. The more gas the turbo can get out, the more efficiently it can force feed your engine with air at the other end.
- While you will probably get some benefit from replacing any part of the exhaust system with performance parts, the benefits are most pronounced when you’re replacing the most restrictive parts of the original exhaust – which tends to be the catalytic converter and downpipe.
- When fitted alongside the correct software, you can get some serious power gains when you replace the original catalytic converter.

How much HP does turbo add?
Supercharger or turbocharger – 
See immediate gains in horsepower by adding a supercharger or turbocharger. While this is one of the most expensive options on the list, you’ll be impressed with the power that each of these add-ons delivers. Also known as forced induction parts, both of these components force air into your car’s engine which improves horsepower and torque.
Are sports exhausts noisy?
8 March 2022 Test sites, laws, offenses, information 
For a tuner’s car is a powerful sport exhaust actually indispensable. Unless it’s a diesel vehicle. Although is also on these some possible, but the self-igniter does not offer the soundscape “worth hearing” for us. It’s different with the petrol engine.
How much HP does headers add?
Do Headers Add Horsepower? – While it may not make as much of a drastic difference as installing a turbocharger or supercharger, investing in performance headers will increase your engine’s torque, subsequently improving your horsepower. Depending on your vehicle type and how much you’ve upgraded your exhaust system, installing aftermarket headers can result in a five percent increase in horsepower. 
How can I add 200 hp to my car?
3. Install a Turbo Kit or Supercharger – Big trucks love turbochargers. That’s because they are fuel efficient and they take your waste heat from the exhaust to boost the air intake pressure. A turbo kit will help your engine become more responsive. You will find turbocharger kits that increase your truck up to an additional 200-horsepower.
Can a turbo add 200 hp?
Previously, you could only find turbochargers in diesel cars and trucks. However, nowadays, most car manufacturers equip turbochargers under the hood. It is almost certain that this device will continue to be used for many years to come because of the advantage of improved traction, helping you no longer be annoyed with the slow acceleration of the car.
How much power can a performance exhaust add?
A well-designed performance exhaust system can increase engine power by up to about three percent. 
Via: autoevolution.com After a flashy set of wheels, there’s probably nothing that gearheads wanting to customize their rides love more than the throaty roar of a performance exhaust system. Not only does the exhaust note add character to the car, fiddling with something that promises to unleash hidden engine power is almost mystical.
However, exhaust design is a more dynamic science than stringing together a few pipes and tacking on some loud mufflers and fancy exhaust tips. In days gone by a performance exhaust system was commonly referred to as a “free-flow” exhaust, with some tuners believing that the best systems were those that did not restrict the flow of exhaust gasses.
We now know that this only plays a small role in unlocking horsepower in most engines, Tuned-length header pipes, often with tortuous routing, that actually scavenge exhaust gases from the combustion chamber are the best performance exhaust systems, for naturally aspirated engines.
Turbo-charged engines have their own set of rules. Tuning an exhaust system to a given application is a case-by-case challenge. The displacement, exhaust valve size, induction system, cam profile, exhaust port design, and RPM range all factor into deciding what form the exhaust system should take. General rules of thumb are easy to grasp, but applying them correctly is where things get tricky.
With the engine running, high- and low-pressure “waves” are manipulated to extract the burned gases from the combustion chamber. To assist in achieving the most beneficial pressure balance between the intake and the exhaust a properly designed header set will exploit two different scavenging mechanisms: Inertial and wave scavenging.
Do motorcycle exhausts add HP?
How To Get The Most Out Of Your Motorbike Performance Exhaust April 22, 2022 A performance exhaust system is one of the best ways to improve the performance of your motorcycle. Allowing exhaust gases to flow more freely can increase power and torque and improve fuel economy.

How much HP does a straight pipe add?
How much hp does a straight pipe add? My sister is advising me to put on a straight pipe instead of doing a muffler delete. How much hp does a straight pipe add? Modifying your car is a great way to make it more powerful! You’ll likely gain about ten hp with a straight pipe as compared with five hp or less by just taking off your muffler.
- Eep in mind that putting on a straight pipe also involves adjusting your fuel injection and otherwise tuning up the car.
- Be sure you hire or consult a professional.
- Important note : In most jurisdictions, putting on a straight pipe means your car can no longer be driven on the street and only be used on a closed track.
This is because a straight pipe is not attached to a catalytic converter and therefore will not pass an emissions inspection, Car enthusiasts are always finding ways to enhance their vehicle’s performance. Another important part of your vehicle’s performance that’s often forgotten is,
