This may be a silly question, but I'll ask anyway. My headers are Swain coated, so they're getting some good insulation. Right when it hits the Y-pipe (which is going from around 2 inch to 2.5 at the merge and then opening up to 3) I would imagine the exhaust is starting to cool. I would think that would be a bad place for that to lose velocity. I have a roll of exhaust wrap. Does anyone think I would benefit from wrapping the y-section and back into the 3-inch by a foot or so?
