I am a relatively new S40 owner, but, with the tremendous help of this forum, I have learned more than I ever would have anywhere or with anyone else! The helpful mentors that have spent countless hours in responding to questions, offering detailed descriptions, and even posting pics of work done have helped me become an expert on every job or mod I attempt.
I purchased the bike on Valentine's day (my wife was all for it), and I have been on this site everyday since then. I purchased it with 3300 mi on it and I have put a little over 400 mi on it since and I love it more and more every time I ride it.
I knew right away the stock muffler was a no go. My wife and I compared it to the sound of the Jetsons mobile. First thing I did was to swap it out with a 2008 HD heritage softail muffler. That worked really well for several months. Right after that I did the air/fuel mix drilling to help with the newly acquired explosions on shut down; I highly recommend it.....the drilling, not the explosions
Was a very easy fix and I now have the CONTROL!!
A week ago I purchased the turnout muffler you see in the pic. Sounds great and feels great. Next on the agenda is some more performance mods....can't wait to get started!
