Took off the driver's side head pipe today to wrap it with the 2" heat cloth and looked inside and found a piece of slag from welding in the O2 sensor fitting hanging down like snot on the inside of the pipe. After around 20 minutes with a grinding stone it was no more. Don't know if it will help performance, but couldn't re-assemble the pipe knowing it was there. Now to wrap both head pipes and spray them down with the silicon sealer.
