How To Straight Pipe A Truck Using Well Researched Steps

Pipe Car

A straight pipe truck is a car with a high-performance exhaust system that provides very minimum pressure as well as improves the top end performance of the racing engine. Apart from your headers, they can be fairly straight with the pipes being perforated which are lined with dampening materials that convert the sound energy into thermal energy.

A normal exhaust system has resonators, catalytic converters and mufflers to minimize emission as well as sound levels. Hence, these can just be used in a closed racing circles and not street legal. The straight pipes basically use the carbon fiber and titanium to minimize weight.

Why You Should Straight Pipe A Truck

Straight piping a car can help you do away with various problems with a custom exhaust for your truck. Also, straight piping a truck improves its speed as well as performance. The process of straight piping a truck is less expensive to create your own system. Few curving and bending means less back pressure that you are likely to experience.

Creating a straight pipe exhaust is not only a challenging technical task but also it does need some mechanical knowledge and the perfect tools to perform the work by yourself.

What To Do Before You Start Straight-Pipping Your Truck

Find out the perfect muffler for your car size as well as type. The size of the muffler itself is of great value since it prevents backflow in the system. If necessary, the kit should consist of a pre-silencer as well as a straight line muffler together with a simple flow-through design.

What Will You Need

  • A hoist
  • Jack
  • Jack stands
  • Reciprocating Saw
  • Metal blades
  • Maker Pen
  • Silicon Lubricant
  • MIG Welder
  • Welding Gloves
  • Welding Helmet

Steps By Steps You Can Follow 

Step 1

Work with the truck in a garage using a car lift. Lift the car using the jack and place it on a jack stands. Make sure that the car is properly placed on the jack stands before you crawl underneath it.

Step 2

Closely the catalytic converter on the exhaust system and locate where the mounts and the hangers are situated. The catalytic converter is an oval section of the exhaust which swells out from the rest of your car’s tubing.

Depending on the year of the converter, it may have vents or louvers on the surface. Draw down your preferred system on a piece of paper, ensuring you calculate the bends you will want to form to skirt the mechanicals at the underside of your track.

Use the metal blades and the reciprocating saw to cut your catalytic converter from the exhaust system, making sure that you keep the saw perpendicular to the tubing so that you can achieve a great, straight cut.

Step 3

Hold the new exhaust tubing against the section where your old exhaust system and use a maker pen to mark the new tubbing to the mark. You can cut the new exhaust tubing according to the marks. Remove the old exhaust from your car. Use a silicone lubricant to make the parts lose prior to removing the clamps.

After removing the old exhaust, disengage your catalytic converter without removing it. The catalytic converter is important for performance and functionality of your truck and it is always needed by the law. Be keen on any clamps or hangers that are wasted and require replacement as you remove your old system.

Step 4

Take your new exhaust tubing and go back and forth underneath the truck to test-fit the sections. If it seems to fit, wear the welding helmet and the welding gloves on, then completely weld the new exhaust tubing together.

Hold the new exhaust tubing just between the two cut parts of the stock exhaust and use a MIG welder which is suitable to tack-weld the tubing in place.

The tack weld is a quick, small weld which secures two parts together but it can easily be removed. You have to ensure that the tubing is placed correctly and there are less gaps at the joints between the tubing prior to continuing with the process. If you there are many gaps left, you will experience an exhaust leak while driving your car.

Step 5

Lower the car off your jack stands using the jack.

In the case of higher horsepower, one important thing that one can do is to eliminate restrictions in the exhaust, to make the exhaust gas flow smoothly. The catalytic converters are very restrictive, and many individuals install a straight pipe in their car to get rid of the catalytic converter completely.

However, this might not be allowed depending on the country you stay in; however, you are using the car to drag racing reasons only, then it should not be a problem.


  • Before you start your process of installing the new exhaust, always allow the car to cool. The catalytic converter can retain a large amount of heat which can burn you if not allowed to cool down.
  • Track-weld the whole system together and inspect for alignment and fit prior to permanently welding the parts together. Always treat the metal for corrosion using heat-resistant paint if the exhaust system is not going to be stainless steel or chrome. An untreated exhaust system will corrode in case the metal is not treated.


Before you start to straight pipe a car, always research on the right steps to do it. The above information gives you a complete procedure on how to straight pipe a truck. You can follow them keenly and achieve your desires.
