I spoke to Borla and they are making an exhaust specifically for the 2017 ZL1 and are done testing it by now. They should be out in two months! I have the part numbers for this which may not be on their web site yet. I will post the part numbers tomorrow. They will be offering the carbon tips as well but will be another two months out for the ZL1. If these were ready in the next week or two I would most likely wait but I already spoke with AFE and going with the below cat back set up. They are making my cat back and should be shipped at the end of this month. I have looked at all options for the 2017 ZL1 with NPP and Borla and AFE are my only two choices with what was out there including Corsa & the Stainless Works (was not a fan). This is what I ordered:
