Looking at pictures guys have posted of their modified 5BW exhausts and comparing them to pictures of the 2016-19 CTS-V exhausts, they sure seem pretty similar. Those 16-19 Vs also have exhaust valves at the mufflers. Considering the 5BW platform is so similar to the previous V, I am wondering if catbacks would work. Borla and Corsa make them.
Has anyone tried this? @WONT TAP - any thoughts on this?
