Straight Pipe Exhaust Overview
The straight pipe exhaust is a type of exhaust system that uses a series of straight pipes to direct exhaust gases away from the engine. Usually, straight-pipe exhausts are used in high-performance cars and racing vehicles because they produce more power and let the engine breathe more.
Though, straight-pipe exhausts might not be legal in some states as they can be pretty noisy. Moreover, these may lead to wear on engine components and increased vibration. So, straight pipe exhausts are not recommended to any driver. But, this type of system can be a valuable car improvement for those who want to maximize their vehicle’s performance.
Advantages of straight piping your truck or car
A straight pipe exhaust will make your car stand out from the crowd
The installation of an exhaust system with chrome-plated piped is the perfect way to make your car stand out of the crowd. The sleek look of these finishing touches will get people’s attention even before they hear the sound of the engine.
You can choose a twin-pipe installation or a sporty look, both of which come with colorful welds in green, blue, or red.
Enhancement in horsepower
The main advantage of using a straight pipe exhaust is that you will notice an increased horsepower. The pressure from the engine is reduced by this system allowing it to work without being blocked by other exhaust flow limiting systems.
This determines a better engine breath and gas flow through the vehicle’s cylinders. At the same time, fuel consumption is more efficient.
Reduce the weight profile of your car
Using a straight pipe exhaust is one of the best ways to optimize your car’s fuel consumption. It is made specifically for race cars and truck vehicles, so you can forget about the catalytic converters and mufflers.
Mufflers are heavy-weight parts that reduce the performance of the car. Also, straight pipes weigh less than stock exhaust systems and perform much better.
Appreciate your car’s authentic engine sound
The car will produce a more aggressive, louder sound due to the straight pipes. Usually, these make a deeper sound than other systems, but they will let you also hear the authentic sound of your engine. And, in case you take part in racing games, it will increase your vehicle’s appeal.
Disadvantages of straight piping your truck or car
It can be pretty expensive
The expense of straight piping your vehicle can be pretty high considering that you have to buy the straight pipe exhaust kit and other accessories and pay for the installation. The equipment and the kit may still be pretty expensive, even though you choose to straight-pipe your car yourself.
It will make your vehicle very loud
Your engine’s noise volume will increase after removing the mufflers. Your car may look more appealing but it might also disturb your neighbors. So, you should take into consideration the tolerance of the areas your drive around before making this car change.
Bad for environment
The classic car exhaust system has a muffler and catalytic converter to reduce the emissions your car produces. Also, it reduces the sound level of your vehicle outside and inside. So, if you remove them and install a straight pipe you will affect the environment both through air and noise pollution.
Decreased resale value
The resale value of your vehicle will be affected because straight pipe cars are not legal in some states and even other countries. This is because specific laws ban most types of vehicle customization.
How Do You DIY Straight Pipe Your Car?

- straight blasted file;
- measuring tape;
- pipe clamps;

DIY Steps to Install Straight Pipe
- Establish the length of the pipe by using a measuring tape. It will be the distance between the outlet of the catalytic converter and the muffler inlet. This should be six inches longer for the joint fittings afterward.
- Cut the pipe after you mark the length to be cut with a pencil. You will then hold the pipe by the vice and use a hacksaw with an HSS blade on it to cut the pipe. Remove the cutting burr using a file.

- In the end, test if you successfully installed the straight pipes and if there are no problems or leaks by starting the engine.
It is recommended to consult an expert mechanic if you are not sure your DIY project went well.
