Step-by-Step Guide
Prepare the Exhaust: Before you begin, ensure the exhaust is clean and free of any oil or grease. This will help the wrap adhere better.
Cut the Wrap: Measure and cut the required length of exhaust wrap. A good rule to follow is to cut 50% more wrap than the length of the exhaust pipe to account for overlapping layers.
Wrap the Exhaust: Start wrapping from the end closest to the engine, ensuring each layer overlaps the previous one by around a quarter of an inch.
Secure the Wrap: Once you reach the end of the exhaust, secure the wrap with metal ties or hose clamps. Make sure the wrap is tight and secure.
Allow the Wrap to Set: Start the motorcycle and let it idle for about 15 minutes. The heat will cause the wrap to shrink and set.
Note: While wrapping your exhaust can make it louder, it’s important to remember that there are legal limits to how loud an exhaust can be. Always check local regulations before making modifications to your motorcycle’s exhaust system.
Using a Cat-Back Exhaust System for a Deeper Sound
Adding a cat-back exhaust system can give your motorcycle a more robust and deeper sound. This system is a popular choice among motorbike enthusiasts who want to enhance the auditory aesthetics of their rides.
What is a Cat-Back Exhaust System?
