2020 C8 Corvette These Headers Lost Power Over Factory Ones... UGH!

In this video we install a set of Kooks 1-7/8" headers on the C8 Corvette with the factory cats. Then we put it on the dyno to realize the gains, only for the big surprise to be that we went the opposite way. We think we identified the reason why and hope Kooks will address the issue. If they do, there will be a follow up video!
