Everytime i turned my engine off, i couldn't touch that pipe because it gets soo hot, hopefully this will net some lower temps. I do reccommend taking the pipe off to wrap it though and probably wait until the engine cools down, I did neither of the above and have a nice blister on my left hand along with a few cuts and scrapes.
