Simple Installation in 7 Steps

Exhaust systems are made of four parts, these include:

  1. Exhaust Manifold

The manifold or header is a single piece of cast steel or stainless steel that is attached to the engine head and delivers the initial combustion gas to the exhaust system. In most cases, the catalytic converter will be connected directly to this before the exhaust piping system.

  1. Catalytic Converter

These are by law requirements in most states, and they convert unburned hydrocarbons, nitrogen, and carbon monoxide into carbon dioxide and water. It is illegal to touch this device unless you are maintaining it.

  1. Muffler

The muffler is the sound reducing component in the piping system, it comes after the catalytic converter, and there are a number of mechanical methods to reduce sound, which I will not delve into here. I have a number of muffler reviews that discuss this part in more detail.

  1. Exhaust Pipe

This is the piping system that connects the manifold to the cat, from the cat to the muffler and from the muffler to the tail. Where there is no muffler, it will connect directly from the cat to the tailpipe. In very old models that don’t have a cat, it will connect to the manifold or header.

When installing an exhaust system, take into account a number of technical issues. The kit you buy must be one that is application defined. The kit should be bought only from a recognized manufacturer and preferably dealer too. Also, make sure you know what performance you want, is it for OE replacement, or is it an aftermarket upgrade/ If its an aftermarket upgrade, what do you desire? Show, sound, racing, power?

Now let’s take a quick look at the seven steps to a seamless exhaust replacement process.

Step 1: Clean out the workspace, make sure you only have your tools and replacement parts.

Step 2: Lift the vehicle with an appropriate jack or jacks.

Step 3: Disconnect your old exhaust system, you will need to use the saw here in most cases. Start by unclamping the pipe from the catalytic converter. If you cannot undo the clamp, saw the pipe.

Step 4: Staring from the converter side, unhook all the brackets from the exhaust system.

Step 5: Assemble the new exhaust system, makes sure to attach the clamps lightly, you will need to make adjustments to the system once it’s fully installed.

Step 6: Slowly but surely work the new system into place, lining up to the OE hanging brackets. If you bought one of the above items or chose a similar product from any of the companies above, such as MBRP, Flowmaster, Magnaflow, etc., you will get an aligned system making your life easier.

Step 7: Once you have installed the entire system you can now tighten all the clamps into place. Once this is done, you can lower your vehicle; you are ready to go.
