Does straight pipe add horsepower?
In some cases, straight piping can indeed increase horsepower and torque. This is especially true for high-performance engines that require a lot of airflows to produce power. By removing the muffler and catalytic converter, the engine can breathe more freely, increasing power.
Benefits of Straight Pipe Systems
Also, with less back pressure, the engine produces more horsepower and torque. Many drivers who race their cars see this as the primary reason to install straight pipes. Your vehicle will accelerate faster and reach higher speeds with a straight pipe system.
Straight pipes offer better flow than many popular performance mufflers. This can be helpful if you're trying to maximize performance and fuel mileage. However, high quality performance mufflers such as Paradox Performance Mufflers offer flow just as good -and sometimes better- than straight pipes.
It really depends on the car. In large part, removing the muffler on a forced induction engine may give you 4 or 5 horsepower increase. Scavenging won't be affected as a few have said if you are retaining the exhaust system and just replacing the muffler with a straight piece of pipe.
Usually not but sometimes you loose the exaust scavenging effect and shift your torque curve into the higher RPMs so your car feels like it has less power when your not flooring it.
Do downpipes add horsepower? Yes. Performance catted downpipes nowadays have been shown to increase horsepower. An aftermarket downpipe with catalytic converters will add 10 to 20 horsepower on average, and that gain is noticeable anytime the turbo spools.
If you're using a street car, you're probably better off with a muffler delete. It will make your vehicle sound better. It will also add some torque, especially for older cars. The cost of a muffler delete is cheaper too.
Does Straight Piping Add HP? In some cases, straight piping can indeed increase horsepower and torque. This is especially true for high-performance engines that require a lot of airflows to produce power. By removing the muffler and catalytic converter, the engine can breathe more freely, increasing power.
You'll likely gain about ten hp with a straight pipe as compared with five hp or less by just taking off your muffler. Keep 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.
That's easy: straight pipes contribute to more power and produce a loud sound.
Does a full exhaust add HP?
Depending on your car, an aftermarket performance exhaust system could give you as much as 50 extra horsepower or as little as 2-3 HP. To learn more about the benefits of upgrading your exhaust system or get an estimate of the horsepower benefits one might give you, try asking an expert.
Car enthusiasts are right when they say mufflers can decrease engine power. Frankly, this applies mainly to older cars—typically, much older ones manufactured 15+ years ago. By removing the muffler, a person may find they gain some horsepower, but usually less than five hp of added power.
Cold Air Intakes are said to improve your vehicle's performance by 5-20 horsepower. This number will vary depending on the make and model of your vehicle. While this isn't enough power to put you back in your seat, it will give your car or truck a little pep in its step.
By removing the muffler, your exhaust noise will significantly be louder. However, the fuel consumption will not be affected at all! In fact – you might even experience a better fuel consumption after installing a straight exhaust pipe.
Straight pipe systems, however, do not include resonators, mufflers, or catalytic converters. This means that the roaring of your engine is uninhibited, resulting in a much louder sounding vehicle.
For example, you may pay anywhere from $75 to $500 in all for a straight pipe exhaust kit and tools for the modification, but letting a shop handle the project bumps it up to an average of $1,500. You can do most of the project yourself and take it to a shop for finishing touches such as welding.
A cat-back exhaust will likely improve your vehicle's performance, including its horsepower. Generally speaking, a cat-back exhaust system can add up to 5 HP, along with boosting the overall performance of your vehicle.
Aside from not making any additional power over a high flow catted downpipe, a catless downpipe is bad for the environment and can also be bad for you, your community, and your engine.
as far as HP gains you will get answers all over the place but we did a back to back test with a couple different systems and average gains were about 15-20whp with a full down-pipe back system with no cats compared to the stock system.
A straight pipe, for example, can cause exhaust gas velocity to increase. This will likely reduce engine performance below 2,000 or 2,500 RPM, making your vehicle a little slower to launch from a stoplight.
Can I remove catalytic converter and run straight pipe?
If you want to use something instead of a catalytic converter, you can use a straight pipe—but you should not remove your catalytic converter to stay street legal. You can use a straight pipe but you will fail smog checks and emissions testing.
Yes straight pipes will be less efficient except, possibly, at one sweet spot. So you will detrimentally effect fuel consumption.
Adding some size to your exhaust pipe diameter really helps your vehicle produce a roaring sound. However, you have to be careful with size – consider only going half an inch or a whole inch. If your pipe diameter is too big, it will create excessive back pressure, negatively affecting your engine and performance.
Of course it will. You will be missing O2 sensors and the CAT.
It makes such a big difference, in fact, that the simple process of redirecting the filter to draw cooler air is good for a horsepower gain of about 5 to 20 ponies in most cars. It might even improve your fuel efficiency, and it'll probably make your engine sound better, too.
If you are questioning whether or not to do a resonator delete, you should do it. It is a simple upgrade that does provide major benefits in terms of sound and performance. Resonator delete upgrades do provide power and torque benefits that are noticeable but not big enough to be a problem to the unsuspecting driver.
Do mufflers add horsepower, or is that just a myth? Reviewed by Shannon Martin, Licensed Insurance Agent. We're sorry you need to replace your muffler. But yes, it's true: mufflers do add horsepower, increasing engine performance by as much as 10 percent or even more, depending on a lot of variables anyway.
Does Downpipe Increase Horsepower? If built right, a downpipe will increase horsepower compared to the stock factory exhaust. Its main purpose is to reduce exhaust gas temperature by directing shot gasses better.
By removing the muffler, your exhaust noise will significantly be louder. However, the fuel consumption will not be affected at all! In fact – you might even experience a better fuel consumption after installing a straight exhaust pipe.
A good muffler not only improves horsepower, but it also adds aesthetics to your car and gives your car a modified look. Great alternative to buying an exhaust system, and much less expensive. With a muffler you are essentially replacing one of the most restrictive areas of your exhaust for a fraction of the cost.
What exhaust adds the most HP?
A cat-back exhaust system improves horsepower because it improves the car's performance. Your vehicle doesn't have to work as hard, and the flow of air is increased.
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.
Depending on your car, an aftermarket performance exhaust system could give you as much as 50 extra horsepower or as little as 2-3 HP. To learn more about the benefits of upgrading your exhaust system or get an estimate of the horsepower benefits one might give you, try asking an expert.

More Horsepower
This is because older mufflers were more restrictive than newer mufflers. Deleting these outdated mufflers will improve exhaust flow and reduce engine back-pressure, and, in turn, provide the engine with more horsepower at higher RPMs.
But just how much does a cold air intake increase horsepower? While it varies from vehicle to vehicle and by company, most cold air intake systems may add around 5 to 20 additional horsepower to your vehicle.

Does a cat-back increase HP?
An Increased Horsepower
The cat-back exhaust system provides a vital boost to ensure the vehicle produces maximum horsepower and torque. The cat-back system has a larger diameter than a standard muffler; the wide opening creates more space for the free flow of air.
