The tailpipe on the stock muffler is not the proper size and therefore an adapter is necessary. Simply remove the bolts at your exhaust opening (there will be 3 or 4) and replace the exhaust tip with The Silent Rider bolt on adapter. The adapter stays attached to your factory muffler and acts as the tailpipe. The adapter will not damage the engine or affect the flow of the exhaust. The Silent Rider will pressure fit onto the adapter. Once the sturdy mounting brackets are properly secured, the installation is complete!
