I figured it was for the diff. because it right by those particular bends, but how much of an issue is heat going to be with the aftermarket systems? I'm not losing sleep or anything, just curious.
What I find strange is the 1st, 2nd and 4th bends seem almost as if they were mandrel bent(a lot smoother), but that 3rd bend is bad, almost as if it were by design, dunno?
