Common Fitment Issues And Solutions

Proper exhaust fitment is not limited to just the connection between the exhaust pipes and the motorcycle’s engine. It extends to components such as the mufflers, headers, and other exhaust accessories.

These elements must be carefully selected and installed to align perfectly with the Harley’s frame and other surrounding parts. Common Fitment Issues and Solutions for Harley Exhaust:

  1. Clearance Issues: One common issue with Harley exhaust systems is insufficient clearance, particularly when installing aftermarket or custom exhausts. This can result in the exhaust hitting other bike parts, such as the frame or bodywork.

Solution: To address clearance issues, you may need to adjust the exhaust system or install additional spacers or brackets. It is essential to ensure proper clearance to prevent damage to the exhaust or other components.

  1. Mounting Bracket Compatibility: Another fitment issue arises when the mounting brackets of the aftermarket exhaust do not align correctly with the bike’s frame or mounting points. This can lead to an unstable or loose exhaust system.

Solution: If your aftermarket exhaust doesn’t align properly, you may need to modify the mounting brackets or purchase additional fender bracket adapters. It’s important to ensure a secure and stable fit to prevent damage or exhaust leaks.

  1. Exhaust Gas Leak: Improper fitment or installation can result in exhaust gas leaks, causing a decrease in performance and potentially impacting the rider’s safety.

Solution: To address exhaust gas leaks, carefully inspect the connections between the exhaust pipes and the headers or mufflers. Ensure all connections are secure and properly sealed using appropriate gaskets or exhaust sealants.
