I have had my SESG for a little over 1 week now. I already had a good idea what I wanted to do and had the parts waiting. When I got the bike it was so restricted I couldn't believe it. It just felt like it didn't want to go. Attached is a picture of my head pipe with about 150 miles on it. Notice the severe bluing after only 150 miles. I added a Fullsac X pipe "B", 2.25" baffles (wanted more noise), and a TTS tuner. The bike is SO MUCH funner to ride!!! You give it the gas and it wants to go. It is a very mellow setup, still not what I would consider loud, it just breaths now. If you think about it, all I have done is unrestricted it. Very mild exhaust, a mellow tune, and it runs like it should. Personally I would do it right away, Steve at Fullsac sells 3 different baffles, medium, quiet, and quieter if you ask me. Like I said, this is my personal experience and opinion, I have to say this bike is a blast to ride now, runs very good all the way around.
