Alright people I am not sure if this was posted before but I didnt feel like going through all the posts. I have a 2005 yz450. I bought the full system white brothers carbon pro exhaust for it. Installed it. Went to do an oil and il filter change and I cant get the top bolt out. Had to remove the header. The clearance is so small that I could definetly dent a portion of the header in so i can get the bolt out without removing the header. I just dont want to dent my 600 dollar exhaust. any idea's????
