This means that parts of the DP cant really be wrapped. Will the exposed portions become a place for all that heat being kept in the pipe to escape and become superheated? I am really, really concerned about this. I will try and get a pic up in a second.
I would not use a header exhaust wrap/tape. They only make your DP's rustout faster, bc the water when it rains get caust between the DP's and the wrap. IF you are really concerned about heat buildup... I would get some thermal coatings put on. Like from www.swaintech.com
