What is the diameter of the stock exhaust on the element? is it 2 1/4? What size are most people upgrading to? 2 1/2?
Don't know about the exhaust size, but it's bolt on. When I had the Injen exhaust installed, the original unbolted-took all of 1/2 hour to replace.bump. Also is the stock exhaust a bolt on? I want to know if I need to cut off the stock exhaust or just remove it.
