Ultra duc and I changed the header pipes out today for pipes with no cats. A friend of ours had a set of stock 09 pipes which we installed on Ducs stage 1, '11. We hac already changed the mufflers to Rhinehart slip ons, the SE air filter kit, and the Gen 3 Dolbeck. It has been running great on factory setting, should the settings change on the Gen 3 after the decatting?:thanks
