A dual exhaust system has lots of advantages. It has better gas mileage, more horsepower, a higher performing and efficient engine, and a distinctly deep, throaty sound that is easily recognizable.

Installing a dual exhaust system is pretty straightforward. It is a good idea to ask someone to help you. An extra pair of hands will come in handy when it comes time to position the new pipes together. Follow the directions below and you’re on your way. Note that the instructions that come with your installation kit will be somewhat different, but this article will give you a good idea of what the process entails.

Step 1: Select and Purchase a Dual Exhaust Installation Kit

Instead of spending hours shopping for various equipment pieces, simplify your task by purchasing a dual exhaust installation kit. The basics of this kit should include a dual exhaust pipe set, muffler, rubber strap hangers, gaskets, clamps, hardware, and installation instructions. Make sure the pieces in this kit are proportionate to your vehicle. The kit should indicate which vehicles it is compatible with.

When you receive your kit, go through it to make sure all pieces are included as advertised. Nothing worse than realizing something is missing half way through the job.

Step 2: Raise the Vehicle

Lift the vehicle, using ramps or jacks stands. This will enable you to work under the car and clearly see what you are doing.

Step 3: Remove Existing Exhaust System

Starting from the back to the front of the car unbolt the exhaust system. Use lubricant to loosen the bolts and make this easier. Remove the parts of the exhaust that you will replace. If you are replacing the muffler, you can either remove the nuts from the muffler hanger, or if this is not working, or use a hacksaw to cut the pipes leading to and from the muffler.

Step 4: Install Exhaust Part

Put the new rubber hangers. It is easier to install these first before the exhaust system. Once done, hang new exhaust part and bolt onto pipe, starting from front to rear of vehicle. Don’t tighten clamps until whole exhaust system is installed; that’s when you make final adjustments. Make sure elbow of pipe is directly above axle.

Step 5: Measure

Measure the front of muffler to the catalytic converter. Cut pipe accordingly and install. Measurements will vary depending on vehicle.

Step 6: Check Alignment

Make sure both exhaust pipes align properly and are even with the bumper. You can tell this by standing back and looking at them.

Step 7: Tighten Clamps

After all pipes are in place, tighten clamps. You may add chrome cylinders to cover the end of the two tailpipes pipes sticking out of your vehicle for aesthetic purposes, if desired.

Step 8: Test it

Lower the vehicle back to ground level. Insert keys and take it for a test spin. If you hear that deep, throaty sound of a dual exhaust system, you know your installation is was a success.
