I bought a set of the older better SE pipes off of ebay. Will the new end caps in the catalog fit them. I noticed in the catalog that there are now 4" end caps and the others, which do I get? The part number on the pipes I purchased are: 65115-98B.

 

Those mufflers were made by Supertrapp for Harley. '06 was the last year Harley offered them. That same muffler is still made by Supertrapp with a part number of 128-65115. The new Supertrapp end caps will fit your older SE mufflers. Go to the Supertrapp web site and check it out. Their customer service is excellent and can help you find what you need if you can't find a pair of the older SE end caps that you like. I believe that your mufflers are 3.5" and not 4". Give Bruce a call at Supertrapp customer svc to verify all my input.

 

Rush end caps fit the old S.E. mufflers and they have a much better selection than Supertrapp.
