I posted this on someone else's post but thought I should start my own to get maximum expossure.
I've got an '09 SERG and have been trying to resolve the same dilemma. I'm not happy with the stock system but not sure about getting some slip ons or getting the cats removed and going with the Fullsac baffles. I want a little deeper tone but don't want it real loud for riding all day. I was interested it Ken's description of the Fullsac sound. Would you go with the 1.75, 2, or 2.5 baffles? Do you need to get the bike remapped afterward?
Another topic. There are those who believe that in this "Obamanation", we are headed down the road where eventually only EPA stamped mufflers will be legal in all 50 states. If that is true, would it be better to buy some slip ons and keep your stock mufflers just in case or damn the torpedos, full speed ahead and have the cats removed and modify the stock mufflers with Fullsac baffles?
