MagnaFlow, an aftermarket exhaust manufacturer, says that its customers can expect horsepower gains of around 10 percent (which is a pretty commonly-quoted figure).
How much horsepower do headers add to an engine?
But the main function of headers is to add some additional horsepower to the engine. You might know that the more horsepower, the better the engine will run. So, headers generally add 10 to 30 horsepower to the engine according to the type of engine and type of headers.
Do exhaust parts make a car exhaust bigger?
That's because these parts just add weight and resistance without actually opening up the exhaust flow from the engine -- it overlaps to give the look of a bigger exhaust, but the same constricted old pipes are still doing all the work. Nope, if you want to experience a few extra horsepower, you've got to invest in high-quality exhaust parts.
How much HP does a Catback exhaust add?
In general, expect a 2-5 percent increase in torque, horsepower, and fuel mileage. But, of course, the amount of power increase you'll experience depends on how restrictive your stock exhaust is.

How much horsepower does a diesel truck gain?
Diesel trucks are a great example – because they generate gobs of torque anyways, adding an extra 35 lb-ft of torque at 3,300 RPM results in a gain of 23hp. This number may seem impressive, but an extra 35 lb-ft of torque at 3,300 RPM isn’t that useful to your typical diesel truck owner. It’s a good increase to be sure, but it’s not usable power.
Does exhaust system add power?
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).

How much horsepower does the S2000 have?
Outfitted with a titanium cat-back exhaust, the S2000 only gained about 3 hp. Plus, most of the gain was in higher RPMs—great for track driving, not as useful on the street. Though, as with Jobe, Fenske did appreciate the sound improvement. However, both the Miata and S2000 are naturally-aspirated.
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.
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.
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.
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.
What is the goal of exhaust system?
Ultimately the goal of the exhaust system is to have the fastest exhaust velocity with the least amount of restriction. The whole idea is to increase the exhaust diameter as the amount of exhaust created by the engine increases. This reduces restriction and allows for more flow.
How to increase exhaust velocity?
It’s important to understand that the velocity at which your exhaust exits is one of the key elements to its performance. The idea behind upgrading typically comes down to increasing the exhaust piping diameter as well as increasing exhaust scavenging by aligning the exhaust pulses in a favorable fashion. When your engine is at low RPM, the amount of exhaust gases leaving is low, so the velocity it exits the muffler is low. You can increase this velocity by using a smaller pipe, but this creates a restriction for running at higher RPMs. Ultimately the goal of the exhaust system is to have the fastest exhaust velocity with the least amount of restriction. The whole idea is to increase the exhaust diameter as the amount of exhaust created by the engine increases. This reduces restriction and allows for more flow.
What happens when your RPM is low?
When your engine is at low RPM, the amount of exhaust gases leaving is low, so the velocity it exits the muffler is low. You can increase this velocity by using a smaller pipe, but this creates a restriction for running at higher RPMs.
How does a muffler work?
Muffler: The muffler also works to eliminate noise by redirecting the airflow through porous pipes, allowing the exhaust gases to expand into sound deadening material , minimizing the noise that finally exits the tailpipe.
What is the first point of contact for exhaust gases after they exit the cylinder head?
Exhaust Manifold/Header: This is the first point of contact for the exhaust gases after they exit the cylinder head. Typically, heavy cast manifolds are swapped out for tubular headers.
What is the purpose of a resonator in an exhaust system?
Resonator: Not necessarily part of the exhaust system, the resonator helps eliminate noise by rejecting sound waves and canceling each other out.
What is piping in a car?
Piping: Routes the air away from the vehicle so the passenger cabin doesn’t fill with toxic fumes.
How much horsepower does an exhaust add to a motorcycle?

What is a Borla exhaust?
A Borla drainage system is located behind the factory catalytic converter where their factory emissions remain untouched. It differs from an excel-back exhaust, which is located on the rear axle and emits louder sounds than its counterpart. Their stinger kits have pre-configured custom mufflers for your car that generate improved horsepower and torque and you love when creating that perfect car note.
What is horsepower in cars?
Horsepower is a specification that buyers should consider when buying an engine for their vehicle. This specification speaks directly to the performance of the car and can tell you how quickly it will accelerate, as well as if it would be able to tow weights or not. For example, higher horsepower engines are typically more powerful than lower horsepower ones but don’t offer great fuel economy in comparison with low-horsepower cars. This may matter most for people who frequently use freeway on-ramps because they’ll want quick acceleration so they won’t lose speed trying to merge into traffic from these offramps.
What does peak horsepower mean?
Figures quoted refer to peak horsepower – These figures rise and fall depending on how fast an engine is spinning or rotating which contributes towards its overall performance levels while driving vehicles such as cars etc.
What is the exhaust system on a 2014 Corvette Stingray?

What does a muffler mean on a car?
Since the muffler (actually, just the tailpipe) is what people actually see, it's one of those visual benchmarks that might indicate whether or not a car has been modified (if you're on the street checking out the competition or maybe shopping for a used car).
How much does it cost to replace a muffler?
According to Midas, it can cost anywhere from $200 to $600 to replace a muffler. Keep in mind this is not the estimated cost to upgrade the vehicle's entire cat-back system.
Do performance mufflers slow down your car?
We're not talking about clamp-on oversize tailpipes -- those won't do anything at all to help your car's performance. In fact, they might actually slow your car down. That's because these parts just add weight and resistance without actually opening up the exhaust flow from the engine -- it overlaps to give the look of a bigger exhaust, but the same constricted old pipes are still doing all the work. Nope, if you want to experience a few extra horsepower, you've got to invest in high-quality exhaust parts. (And a cheap imitation "aesthetic" add-on won't give you the aural benefits, either ... but a real one will.)
Does it hurt to upgrade a cat back muffler?
It doesn't hurt to upgrade the muffler on its own, especially if it's a rusted-out mess and you need to replace it anyway.
Does it hurt to replace a muffler?
It doesn't hurt to upgrade the muffler on its own, of course, especially if it's a rusted-out mess and you need to replace it anyway. But the gains, if any, will be minimal. Replacing your car's muffler alone is not enough to open up the restrictive exhaust system and allow the extra airflow that increases performance.
What is a modded engine problem?
A common problem with modded engines is a combination of spiking AND boost creep. That's where you're set for 13 psi, and when you floor if it overshoots to 16 psi, *begins* to drop back down, but as the rpm's rise it goes up again!
What headers do NA cars use?
NA cars typically run best with equal length headers that have primary and collector tube sizes matched for the power band the intake and cams are setup for.
Where should the restriction be on a turbo car?
The only major point of restriction on a turbo car should be between the exhuast ports and the turbo. From the turbo gradually expand from the turbine exducer diameter to the diameter of exhaust that matches the power level you are looking to produce.
Do turbo engines need exhaust?
Exhausts do help a lot on turbo cars.
Is exhaust a multiplier?
Exhaust is more of a multiplier than a hp adder. When I added my downpipe and test pipe I did gain almost an entire second off my 1/4mile. While it might add 10-20 hp to a T-25, the difference would be much greater if you were running stock exhaust with a 16G. Like cucumber says go with new exhaust. A test pipe will help but you will be a lot louder.
