At the root, straight pipe exhausts are not that different from standard exhausts, except the exhaust pipe runs all the way from the exhaust headers to the end, without any catalytic converter or muffler working to reduce the noise .

So now, theres nothing stopping the exhaust gases from running freely through and flowing out the exhaust tip. This results in the sound that motorheads love and go crazy about, and most older neighbors hate.

Now, there are a lot of people love straight pipe exhausts and another bunch of people who hate them. Lets take a look at why people are at such extreme poles when it comes to these noise minting bad boys.

Straight Pipe Exhaust Kit

There are lots of straight pipe kits for different models of cars, and you just have to choose the one that will fit yours.

Before installation, you need to confirm if the diameter of the pipe will work well with your vehicles model. This is the universal one I recommend on Amazon

If you want to operate on a 4-inch design, then you should not equip your car with a lesser circumference pipe. Find the kit that is compliant with your vehicle.

Another thing you should consider is the service charge of installing the straight pipe kit in your vehicles exhaust system.

Recap: How Do Car Engines Generate Power

Before we jump into how straight piping and cat-back exhaust can boost horsepower, we must first understand how car engines generate power.

Cars deliver power by generating combustion in the combustion chamber. Combustion is a controlled explosion thats produced by igniting fuel injected into the combustion chamber.

From what science tells us, combustion uses up oxygen to exist. This is why your car constantly sucks air from the outside and delivers it to the combustion chamber the more oxygen in the chamber, the bigger the combustion could be.

To boost horsepower, extra oxygen and fuel are needed in the combustion chamber. Injecting extra fuel is not a problem, getting the extra oxygen is. Every performance modification aims to somehow increase the amount of oxygen in the combustion chamber. Examples: aftermarket exhausts, turbos, nitrous, etc.

Where Do I Buy One

Straight pipe anyone

There are plenty of customs exhaust shops that will help you to identify and source what you need. A quick search on Google gave me a number of garages within a 20-mile radius claiming to work with straight pipe exhausts.

Ring the shop first before you decide to buy from them. Its a good way of getting a feel for the people who work there and the type of company it is. If the staff who speak to you sound stressed and bothered, dont expect the service to improve after youve decided to go with them.

Also look at the outfit theyre running perhaps by driving past or searching on Google Street View. If the shop is in a grubby part of town or looks run down, youd probably best avoid it. Why go for a supplier or fitter that cant afford to look after their premises?

For such an important modification to your car, you want to make sure you get the best you can. It will pay dividends in the long run.

If youre looking for a straight pipe exhaust for your Toyota Tundra, there are plenty of tundra exhaust options out there. Even if youre on a budget, you can find the right exhaust system for your truck and impress all of your friends.

    Recap: Whats Straight Piping

    Fun fact: straight piping has nothing to do with it being straight. Instead, straight piping means removing the catalytic converter , resonator and muffler from your exhaust system. This means your exhaust system is only made of a straight metal pipe thus straight piping.

    The idea of straight piping is that by removing the above components from the exhaust system, we remove unnecessary restrictions and allow exhaust gases to flow with ease and exit the car quickly.

    How does this relate to horsepower? You see, when a combustion is generated, exhaust gases are produced. These exhaust gases are toxic and they occupy the combustion chamber. The exhaust gases must exit quickly to provide space for new oxygen to enter for the next combustion cycle.

    The faster the gases can leave the chamber, the more new oxygen can enter. Which means we can generate a bigger combustion for more horsepower.

    As a side effect, cars with straight piping will be highly pollutant and noisy. This is because the CAT which cleans the exhaust gases is removed. And so is the muffler and resonator. If you dont already know, mufflers and resonators significantly reduce the noise coming from an engine.

    Straight piping is suitable for racers who absolutely need the extra horsepower and are only driving on track.

    Does Straight Pipe Waste More Gas

    how to put a straight pipe on your car

    The short answer is no. In the old exhaust system, there is usually a catalytic filter that filters out dangerous gases and only allows harmless gases to come out of the cars exhaust. But with the new straight pipe exhaust system, nothing is filtered out.

    It is supposed to literally set the engine free to breath and roar as it pleases. The trouble is the environment pays the price.

    This is perhaps why straight pipe vehicles are unlawful in many countries. No country that understands what climate change is doing to the environment and economy would encourage behavior that further endanger the environment.

    If you care about the environment, maybe try to resist the temptation of getting a straight pipe exhaust system.

    We all need all the oxygen and environmental support we can get. The ozone layer weaken by the minute.

    straight pipe exhaust sounds are exquisite and alluring to car lovers, but everything shiny and good looking is not always good for us.

    Exhaust System Upgrade Rules Of Thumb

    In summary, your OEM exhaust system is better than you might think. While it can be improved upon, you need to be careful about how you modify it. Generally speaking:

  • You never want to delete or remove anything. Removing a muffler or catalytic converter can really screw up engine performance. The cylinder head, exhaust manifold, and factory exhaust are a tuned system. If you remove one of the pieces, youre far more likely to lose power than you are to increase it.
  • Buy a tuned system if you can afford it. A tuned cat-back system is a great upgrade, as its dyno-tested and proven. Theyre also usually built to OEM specs .
  • If you cant or dont want a tuned system, make incremental changes. If you really want to delete your muffler, try replacing it with a straight thru muffler instead. If you dyno the car before and after, youll be able to see how your new muffler impacted performance. Then you can decide if you need to delete the muffler or put the factory muffler back on.
  • Understand the impact that tube sizing has on performance.This chart shows ideal exhaust tube diameters for various engine power levels. While the chart is a rough tool, its a good reference when youre sizing a muffler, etc.
  • Good luck on your next exhaust upgrade!

For many motorheads, this is an absolute no brainer more horsepower equals better vehicle. In many instances, there is also a notable increase in fuel economy.

    Looks Matter

    This is a deal-breaker for many streetcar fans. There is a belief that a car must reflect your personality, and you dont get this with cars fresh out of the factory.

Straight pipe exhausts seem to give motorheads the ability to show off their true personality and make their car truly their own.

    Letting The Engine Roar

    As we mentioned earlier, the engine is at its most natural, loudest form when it isnt held back by the muffler. This is a major reason why most fans prefer a straight pipe system. Theres something about the sound of an untamed engine that just feels right. And thats what gets motorheads going.

    What Is The Difference Between A Straight Pipe And A Downpipe

    There are several key differences between the two exhaust systems. Straight pipes produce many gases, while downpipes have catalytic converters that reduce the emission of harmful gasses.

    A straight pipe can be illegal, mainly because of the emission, while downpipes in most countries are legal. A downpipe is more expensive to install. Straight pipe installation costs between $1000-$1500, while a downpipe can cost between $2200 $2500.

    You can easily install a downpipe yourself, but a professional would be best with the straight pipe as it even involves welding. Straight pipes produce louder noise than downpipes simply because they have no distractions as they are just straight, exposing the engine sound more.
