Ok so many of you probbably seen i installed my Ti Force full system . I noticed 1 of my 4 headers only turned the purple cover up by the flange while the other 3 turned purple about half way down the pipe any reason for this . The pipe is one of the inner 2 i beleive headpipe number 3. Was just curios what would cause he other 3 to turn alot more purple then the one other..
