Step-by-Step Guide to Installing Your Motorcycle Exhaust System


A Motorcycle exhaust installation is an upgrade that can add power, a unique look or a particular sound. Before beginning any modification it is important to understand the goals of the project.

Be aware that changing the exhaust will likely require rejetting. The OE manufacturers must design the fuel systems to run on the ragged edge of lean, and any less restrictive exhaust will likely cause the bike to need rejetting.

Removing the Exhaust

The exhaust system on a motorcycle directs burnt gases away from the engine. It also contributes to performance and style. It can give a bike more power, a deeper sound and a grittier look. However, it’s important to remember that any modifications must be done within the law to avoid legal issues in the future.

Before beginning any work on your motorcycle exhaust, allow the components to cool down. Then, review the installation manual and make sure you have all the necessary parts. The manual should indicate what’s needed, but we recommend grabbing a couple extras, like replacement header gaskets.

These can be easily damaged when removing the old exhaust, so they’re well worth having on hand. Likewise, a bottle of penetrating oil is handy for dealing with stuck bolts and rusted clamps. It’s also a good idea to keep some rags and contact cleaner handy to wipe down the hardware afterward. This will help prevent corrosion and rust in the future.

Removing the Muffler

The exhaust system is a crucial motorcycle component that directs burnt gases out of the combustion chamber. It can come in several shapes and sizes and a variety of finishes to improve performance and aesthetics. The system includes the muffler to reduce noise and the catalytic converter that manages emissions and reduces harmful carbon monoxide, nitrogen oxides, and hydrocarbons into oxygen, water, and carbon dioxide, which are much less toxic for you and the environment.

Replacing the muffler with a lighter aftermarket model can boost power output by allowing your bike to breathe more freely. It can also provide a more aggressive sound, but always make sure to stay within the legal limit for your area. This is why it’s important to take stock of your mechanical aptitude and the tools at hand before you start making changes. Stripped or seized fasteners are common with exhaust systems and can be difficult to fix without the right equipment.

Loosening the Connection Joint

A new exhaust can make your bike look great, and the job is not difficult or time consuming. Before beginning, check that the bolts and clamps holding your stock exhaust in place are tight enough to hold the new pipe. If you are using a torque wrench, follow the manual’s specifications to avoid overtightening that can crack your pipes.

If you are replacing a muffler, it’s wise to purchase a set of replacement exhaust port gaskets. Loose gaskets can let oil leak out and damage your engine.

Most aftermarket motorcycle exhausts have a chrome finish. When they are exposed to high temperatures, the steel tends to discolor. A good way to prevent this is to use mufflers with extensive heat shielding. In addition, it helps to have properly gapped spark plugs and lean jetting on a well-tuned motorcycle. Also, buying double-walled pipes is a good investment that can eliminate corrosion problems caused by heat exposure.

Installing the Slip-On

Exhaust systems are available in a wide array of styles, materials, and finishes. Stainless steel, titanium, and carbon fiber are common options. Aside from enhancing the sound of a motorcycle, these exhausts also make for significant style upgrades. Unlike full-system exhausts, which replace the entire system, slip-ons focus on replacing the muffler only.

Because of their user-friendly design, slip-ons are a popular modification for motorcycle owners looking to upgrade the look and sound of their ride without spending a fortune. In some cases, they may even be able to provide a modest power boost for those who are seeking a little more low-end acceleration on their bike.

Before starting any work on your motorcycle, always double-check that you have all of the recommended parts on hand. Additionally, it’s a good idea to carefully read the manual that comes with your new muffler or consult the specific instructions for your chosen aftermarket exhaust. Additionally, be sure to sanitize any tools you’re using before and afterward to prevent the spread of germs.
