When I bought my 2010 SG, I had the dealer throw on the SE Nightstick on the exhaust because I did not want to leave the dealer quiet. I drove with the Nightstick on since last Oct and over this weekend I pulled the trigger and bought a set of Rinehart True Duals. Installed them myself in about 2 hours, cleaned up the pipes and fired her up. What a great sound. Unbelievable. I am truly happy now with the sound of my bike. And I love the look of the duals coming sticking out back. I don't know why Harley went to a 2-1 pipe, but it's obvious by looking at the 2011 models that they listened to the people and went back to the duals. Best part of the deal is I found the pipes through searching the web for $780. I went down to my dealer and told them what I could get the pipes for with free shipping and asked them to match. Parts guy said there's no way. But I spoke to the manager and he approved it. So do ask when you find great deals. Now I have my Nightstick slip on for sale. It has a great sound, but I wanted the dual look.
