Exhaust Extension Kit

What Is an Exhaust Extension Kit?

An exhaust extension kit is used to extend the length of the exhaust system beyond its original configuration, typically added to the end of the existing exhaust pipe to alter the exhaust exit location or to provide additional clearance for body components. Whether you're building a custom street machine, prepping a circle-track race car, or simply dressing up a touring motorcycle, extension kits give you the flexibility to route exhaust gases exactly where you need them.

Extensions can be made from various materials such as stainless steel or aluminized steel to ensure durability and corrosion resistance, and are commonly used in custom exhaust setups or when modifying the exhaust system to meet specific requirements or preferences. While primarily used for fitment adjustments, an exhaust pipe extension can also improve airflow and help optimize exhaust gas flow.

What to Consider When Shopping for an Exhaust Extension Kit

Choosing the right exhaust extension kit comes down to a few key factors:

• Pipe Diameter: To accurately measure your exhaust system for the correct pipe diameter, measure the outside diameter (OD) of your existing piping — the most precise way to do this is with a caliper.
• Shape and Angle: Consider the shape and design of the extension, such as straight or angled, to ensure it aligns with the exhaust system and the vehicle's body.
• Material: Stainless steel offers excellent corrosion resistance, meaning it's highly resistant to rust and degradation from road salt, moisture, and exhaust gases, and also provides high strength and durability capable of withstanding extreme temperatures and vibrations without cracking or deforming.
• Universal vs. Vehicle-Specific Fit: Some extensions are universal, but it's important to check dimensions to ensure proper fitment with your specific vehicle and exhaust system.
