hello all i have an 07 deluxe with true duals on it and when i installed the pipes the rear 02 sensor was stripped so i installed a new one. my question is the front pipe is real blue in color coming off the head and the rear is brownish yellow doesnt seem normal to me i am also runing a v&h fuel pack wonderinf if any one could help me out much appreciated!!!!!!!!!

 

sounds like you need to get that thing tuned.

 

make sure you are running the exact map for your model, year, and pipes from the V&H site... first time I set mine up I used the map for the 08's cause thats all that was in the instructions, didn't work worth a $hit.
