Exhaust systems are a series of pipes that take the exhaust gases expunged from the combustion cylinders through the manifold head and out to the air. Most exhaust systems come with various configurations of the header or intermediate pipes, crossover pipe, catalytic converter, mufflers, and tailpipes.

F-150 Exhaust FAQ
There are three main types of exhaust systems on the market; these are header-back, cat-back, and axle-back.
Header-back exhaust systems
This provides a complete replacement for every component from the engine header to the tailpipe. These systems provide more flexibility in design, and you can enlarge the diameter of your entire exhaust system for greater exhaust gas flow. These models are more expensive and harder to install than other systems.
Cat-back exhaust systems
These models start the exhaust replacement sequence form the catalytic converter back. They generally come with a replacement muffler and tailpipe; some kits come with a mid-pipe, X-pipe, H-pipe or a Y-pipe. These are the most popular upgrades and replacement kits since they are budget-friendly, easy to install, provide a state legal replacement from the catalyst, and deliver deeper and more aggressive tines.
Axle-back exhaust system
These are the classic stock replacement models that come with the components to connect from the rear axle to the tip. They provide better performance than standard stock replacement models and are the easiest and cheapest to install. Some models deliver performance sound.
There are also two configuration options, a single or dual exhaust.
Single Exit Exhaust
These are the common models and provide a single tube, muffler to tip tubing. These are lighter and less expensive than the dual exit models.
Dual Exit Exhaust
These use the same components as a single exit system, they come with one head pipe, converter, and muffler, but end with two exhaust tips rather than one.
True Dual Exhaust
When it comes to the aftermarket scene, true dual exit exhaust models are the most popular, these come with two of everything, and they run from the header to the back on either side of the vehicle.
These kits provide a sporty look and deliver a distinctive growling sound generated by the two mufflers. The only issue with a true dual exhaust system is the imbalance between the two components that can lead to cylinder head issues that reduce HP. To combat this, a crossover pipe is installed that lets the gasses from both sides mingle, and create a single pressure flow for both systems.
Exhaust Material
The two materials you will find are either miss steel or stainless steel. Mild steel needs to be coated to prevent corrosion and is an inexpensive material. Stainless steel is less corrosion-prone and more expensive.
How to Install and Exhaust
Changing an exhaust is relatively simple unless you get a header back system that requires you connect it from the header (or manifold in turbocharged models) to the tail.
There are two ways to replace the exhaust either lying down, or standing up, and that’s dependent on the jack you have. If you have a good floor jack with support beams, then you do it standing up, and the operation is much quicker.
Whether standing or lying down, prepare the parts in the order of installation, and have all the hardware and tools ready.
- Perform a dry test and connect the new system to see all the parts fit together, you don’t want to start and find out you have a mismatched component in the middle of the change.
- Start by unbolting the old exhaust system from the back work towards the front.
- Remove all the parts, and keep the hangers just in case you need extra from the hardware you have.
- Start by placing the new hangers into their place.
- Once all the hangers are in place, you start from the front of the vehicle and hang all the exhaust components.
- Bolt the upstream pipe into place, but don’t torque it yet.
- Now connect all the parts, and once all connected, go back to the front.
- Torque all the parts into place.
- You are all done and ready to go.
