1 pointI can confirm. The clip arrangement is a right royal PITA around the exhaust. I did post some pics but they were lost when the photo sharing app stopped allowing free stuff I think I might still have them some where. Another tip especially at this time of year is to keep all the plastic warm. It helps prevent snapping clips and gives you a little more margin to flex stuff without damage. Good luck!
1 pointYes the existing surround does fit. I only purchased the two diffusers and used the original surround. I had my diffs painted gloss black and wish I would have done the surround as well but it still looks good as is. I also changed my front bumper set up to the GTS as I think it looks so much better.
