Due to a recent accident, I have to replace my bumper and exhaust on my '07 Escalade ESV. I wanted to upgrade the exhaust and bumper to the '12 dual exhaust look. I have seen threads on this forum that showed the conversion costing roughly $1200. Could you tell me the difference between the cost of a '07 bumper cover and exhaust and the '12. I will likely have to pay the difference out of pocket, so I am not looking to pay too much. I would have all repairs done in the collision center at Rippy. Thanks.
