Back again with another question. I am looking at the HMF slip on for my 09 1125R. Has anyone installed one and if so what kind of sound and performance did it give? I am looking for something with a little more sound but not too loud. In the past I have taken aftermarket mufflers and made my own inserts to quiet them down a little. Are any remaps required to run this type of muffler with or without an insert? Thanks much! Crewdog
