I have an 04' efi sno pro f7. last year i put on D&D's bulls eyes, fuel pressure regulator and a can and everything worked great. this year i put on the D&D y-pipe and i started to bogg really bad. looked at my plugs and they were soaked, oil leaking out of my exhaust. 3 mechanics told me to change back to the stock y-pipe and the guy from D&D told me it was an electrical problem. I have lots of power until the midrange, then it starts to bogg and someitmes can't get past 65mph. changed backed to stock y-pipe and worked better for first 20 miles, hit 97mph standing up but the last 20 couldn't get past 85mph crouching. what is going on with my sled.
