Straight piping reduces engine stress caused by exhaust gasses, resulting in increased horsepower. The less pressure on the engine, the better it will function, which leads to greater torque and hp.
A number of components surround the exhaust system, including mufflers and catalytic converters. While they may not be harmful to a vehicle, they do limit the engine’s power.
Straight pipes remove those items and allow a smooth engine flow. This way, the engine performs to its fullest potential. With its full power unlocked, the horsepower increases significantly.
It is obvious that a straight pipe increases hp, but by what amount? I will answer that in the following paragraph.
How Much HP Does A Straight Pipe Add?
A straight pipe adds around 10 or more horsepower to your vehicle. However, cheap pipes won’t provide your car with more than 5 hp, whereas high-end straight pipes can bring your diesel engine’s output up to 10 hp.
The cheap ones certainly look like straight pipes but are ineffective at ensuring adequate exhaust flow. As a result, the hp gain is very minimal or non-existent at times.
Rather than buying a subpar straight pipe, you can simply remove the muffler and get a mere 5 hp. Hence, I would recommend you to go for a high-quality straight pipe if you decide to buy one.
How Much HP Does A Straight Pipe Add To A Diesel?
Diesel and other engines do not vary a lot when the vehicle is straight piped. Thus, diesel-powered automobiles can also achieve a boost of 5-10 hp from straight pipes.
Straight piping is the best option for your diesel truck if you desire more power. In contrast, other upgrades such as x-pipes will only add about 5 hp to your vehicle.
Do Straight Pipes Reduce Horsepower?
A straight pipe won’t reduce horsepower but rather increase it alongside your vehicle’s torque. This is because they improve the flow of the engine, ensuring it runs more smoothly.
If the pipe does not generate any additional horsepower, the car will maintain its original hp without sacrificing any performance.
Does A Straight Pipe Make Your Car Faster?
A straight pipe will make your car run faster by increasing hp. While horsepower is not the only determining factor for speed, it still plays a significant role in acceleration and top speed.
Moreover, when you straight pipe your automobile, you remove some of the devices (converter, sensor) that interfere with the engine’s performance. Without them, your car will certainly run faster.

Does Straight Pipe Make Car Slower?
Even though it is rare, straight pipes can cause exhaust gas velocity to rise. This adversely affects the engine’s performance when it is running at 2,000 or 2,500 RPM. As a result, the car might run slow, especially while launching.
There is an easy solution to the problem. Simply tune your straight pipe to suit your vehicle.
A good tuner will ensure that your car will not slow down due to the straight pipe.
Is Straight Pipe Better For Performance?
Performance-wise, a straight pipe is unquestionably superior to other pipes. It offers very low backpressure while at the same time maintaining a high flow rate of the engine. Both of these factors are vital in maximizing the performance of a car.
Aside from performance, straight pipes also contribute to improved fuel economy and a pleasant (or should I say loud?) sound.
Conclusion
Hopefully, now you know straight pipes can increase a little horsepower or more depending on your vehicle. I personally rate the straight pipe more highly than other pipes or a muffler delete based on its hp gain.
