Worse part about it is they don't come polished or ceramic coated like the pipes do , lol
They will ceramic coat them if you wan't inside and out. I personally don't like ceramic on a 2 stroke pipe. It holds a lot of unwanted heat in the pipe. I like plain, with a good seasoning of atf on it, or chrome/nickel plate. I have the First new style AAEN pipe ever made. it's a hybrid pipe, my frame is the one the jig was built from. The zilla pipe came later and was built off a tweaked chassis, hence the fitment issue with the zilla pipe. Joe Rock wanted a shiny, big sparky silencer for SL and thats where the 2nd silencer version came from.
