Whether you are a novice or a seasoned auto enthusiast, this guide will be detailed enough for anyone to understand the process. You’ll learn what tools and materials you need and how to install the new exhaust system properly.
How to Straight Pipe a Car ?

Straight-piping a car can give it an extra boost of horsepower and speed. It is a relatively simple process that can be done in the comfort of your garage. Straight piping involves replacing the car’s existing exhaust system with straight pipes, simply pipes that run from the engine to the tailpipe without any bends or curves. This modification increases air flow and reduces back pressure, improving engine performance. Here’s what you need to know if you’re looking to pipe your car straight:
Materials Required for Straight Pipe in the Car
- Steel
- Aluminum
- PVC
- Wood
- Metal
- Plastic
- Rubber
Necessary Tools for Straight Pipe in the Car
It’s important to note that straight pipe installation should only be done by experienced mechanics or those with adequate knowledge and understanding of adequately installing exhaust systems. Here are some of the necessary tools you may need when straight piping your car:
- Screwdriver
- Needle nose pliers
- A grinder
- Pipe cutter
- Pipe wrenches
- A rubber mallet
- Cordless drill with a Phillips head attachment
- A bolt cutter or hacksaw

The Process to Straight Pipe a Car
In straight piping,” a car removes the catalytic converter and replacement with a straight line. This process can be done for both performance and aesthetic purposes. However, it does come with certain risks. Catalytic promoters are emissions control devices (ECDs) that help reduce the number of harmful gases released by the engine into the atmosphere. Still, they can impact your vehicle’s performance if they are removed. Here we will discuss how to pipe a car safely and effectively.
Step 1
Your car’s ideal size, brand, and model will determine which parts you need for straight piping. The diameter of the muffler will also play an essential role in this process – choosing one that’s too large can cause backflow in your engine while selecting one that’s too small might leave you disappointed with its sound quality. That’s why knowing all these details is essential before starting the job yourself or taking it to a professional mechanic.
Step 2
You will need a vehicle lift in a garage or driveway, and your present exhaust system should be disconnected. It’s also helpful to illustrate where the desired account should go before beginning work. Skirting the electrical organs of the car is essential, so you don’t cause any damage.
Step 3
You must safely dispose of your old exhaust system components, such as the muffler and hanger. You should also remove any broken straps or clips that may have been holding them in place. If present, the catalytic converter must also be removed using pliers before continuing. In some cases, a jack may be necessary if a particular component is difficult to reach without raising the vehicle slightly.
Step 4
The next step involves cutting and preparing mandrel bends for your exhaust system. A mandrel bend is an elbow-shaped tubing piece that allows smoother airflow by preventing folds or kinks in your exhaust pipes. Using quality mandrel bends when constructing an exhaust system is important, as this will help minimize back pressure and increase performance. Once you have all of your pieces cut out from the mandrel bend, it’s time to start assembling them underneath your vehicle.
After the pipe components have been tack-welded, coat the mandrel with paint and corrosion protection. The exhaust parts of your car should be painted based on the material.
Final thought about how to Straight Pipe a Car
Straight piping a car is challenging, and many people are worried about how to straight pipe a car, but it can be done with the right tools and guidance. The process involves several steps that can be completed in a few hours if all parts are available. It is important to remember that modifying any vehicle can affect its performance, so it is important to research and understand any potential risks before beginning the project. Additionally, care must be taken to ensure that all parts are correctly installed for optimal performance and safety.
