install sucks on the bde systems, the #1 and 4 head pipe hit the oil cooler lines, once you bend them out of the way it is a piece of cake. I love mine i put it on a few days before i was deployed to Romania with the Army. I can post a few pics of what the install involves when i get back to the states. After everything was done it was well worth the extra effort for the brock system... (bde street megaphone)
