I can provide some general information, but please keep in mind that specific warranty policies may vary between manufacturers and dealerships. It's always best to consult the warranty documentation or contact the authorized dealer for accurate information regarding your particular situation.
Modifying or replacing parts on a motorcycle, such as installing a new muffler, can potentially impact the warranty coverage provided by the manufacturer. Many warranties include provisions that state modifications or alterations to the motorcycle, including aftermarket parts installations, may void certain aspects of the warranty.
Some manufacturers may allow certain aftermarket modifications, while others may require the use of genuine parts or components approved by the manufacturer to maintain warranty coverage.
To determine the effect of installing a new muffler on your Harley Davidson's warranty, you should review the warranty documentation provided by the manufacturer or contact an authorized Harley Davidson dealership. They will be able to provide accurate information based on your specific motorcycle model and warranty coverage.
Remember, it's important to keep any documentation and receipts related to the modifications made to your motorcycle. This can be helpful in case any warranty-related issues arise in the future.
