How To Add Back Pressure To Straight Pipes?

With exhaust pipes carrying an excessive amount of load, engines are faced with the potential for damage due to increased pumping work and lowered boost pressure in the intake manifold. Solutions such as straightening out curves and vents can help reduce excess flow but must be paired with backpressure implementation — which reduces both system overloads from too much pressure, as well and starting problems frequently induced by lower-than-normal pressures. Through proper use of a muffler here, you’ll benefit from improved engine performance through reduced strain on your entire machine.

Maximizing Engine Efficiency with Straight Pipe

Unsure of how to add back pressure to a straight pipe? Don’t worry! Here is an easy-to-follow guide that will have you master the process in no time. Learn more about adding back pressure and find peace of mind with this step-by-step solution!

Step 1: Gather the Necessary Tools

The prerequisite for starting any work is to keep all the necessary tools and furniture in your collection.  It is very important to keep useful things with you when you want to install the pipes.  In this case, the tools you need are:

  • Stainless Steel Straight pipe
  • Measuring Tape or scale
  • Pipe fastener
  • Hacksaw or grinding saw
  • Sharp hacksaw blade
  • Pipe Vice
  • Adjustable wrench
  • Safety goggles
  • Hand gloves
  • Face mask and heat resistance gear

Step 2: Setting The Pipe Length

It is important to measure the distance or length of the muffler inlet and the outlet that exists in the catalytic converter. You need to use measuring tape or scale to measure the accurate distance.

You need to increase the distance between the two by at least 4 to 6 inches.  For example, if you get a length of 10 meters then keep 16 meters or 14 meters.  If you do not keep the extra length, you can’t fit the slip joint correctly.

Step 3: Cut The Pipe Accordingly

After measuring thoroughly, now, time to cut it according to the measurement. To cut the pipe accurately, go through the following point.

  • Hold the pipe with a pipe vice or clamp.
  • Take a marker or a pencil and mark it to the right length.
  • Then, cut the pipe with a hacksaw putting in a new HSS hacksaw blade.
  • Cut the extra edge or border if it exists.
  • Finally, take off the cutting burr with a file.

Step 4: Take Off The Old One

Now, time to remove the old ones that are already worn out. Take your wrench and loosen the nut of the exhaust. Then, take off it from the intake using the full force of your hand. You can get assistance from your family and friends if they are.

Cautious: Please check repeatedly and ensure the pipe is cool enough to hold. If the pipe is hot, your hand or body will be burnt completely.

Step 5: Install The Pipe

Before installing, look at the carburetor or catalytic converter. In most cases, they would also be broken and ruin your entire system. If you are sure that they are excellent in condition, add the ending part of the straight pipe with them and the tailpipe.

The number of pipes you need to install depends on the type of vehicle. Fasten the pipe joint by welding or any other jointing approach.

Step 6: Adjust Back Pressure

After installing the pipe, align the clamps and tighten them as much as needed. Before that, make sure you are bending or aligning the pipe accurately.

After that, add back pressure to reduce the extra flow of the fuel and gas. By adjusting the pressure, you now stop over-fuel consumption. 

Step 7: Test The Back Pressure

When you are done with attaching back pressure to the straight pipe, now, test if the pressure is accurate. There are many methods to test and check the pressure level.

Why Installing Backpressure to a Straight Pipe is Essential

Backpressure can reduce overflowing gas and keep the engine stable. Moreover, if you add the backpressure to the straight pipe, it can protect the pipe from earlier damage. Here are a few reasons to clarify your idea.

Helps the engine to run at peak efficiency

Engine efficiency is a crucial thing to running your car effortlessly. If the engine goes wrong, your driving experience will be ruined. Adding backpressure means you are extending the efficiency of the engine. As a result, you can’t face any hassle of starting or heating your engine before driving.

Reduce friction between flowing exhaust gas and inner wall

Too much friction destroys the entire piston. As a result, you need to pay extra money for extra fuel. The higher the friction, the more fuel is consumed. The higher the friction, the more fuel is consumed. Fortunately, the standard level of backpressure can reduce friction and make the fuel flow smoothly.

Produce standard exhaust flow

Exhaust flow or gas flow is mandatory to keep your vehicle on track. If the gas flow is too lean, the efficiency of the motor will reduce. Besides, carbon particles clogged in the air filter and exhaust pipe produce harmful gas.

To get rid of all these problems, adding backpressure is your penfriend. So never be late to do this. If so, you are going to lose your car performance.

Increase fuel economy and power

With increasing power and efficiency of the engine, it can simultaneously improve fuel economy. This is why you can save your extra money to add fuel over time.


Many experts and car owners give their opinion not to add backpressure. But this myth is outdated. There are many benefits of adding backpressure to a straight pipe simply called ‘Y’ Pipe. To make gas flow stable and reduce excessive pressure, there is no substitute to add back pressure. So stay tuned with including backpressure.
