So, SFDownhill hooked me up with a Wolf exhaust and my thinking was it wouldn't mate to my TBros header so I'd need a stock or equivalent header replacement. No oem fitting pipe I ever tried would work with the TBros header outlet that is angled to work only with their mid-pipe.
But, with just a little fiddling, the two-piece Wolf pipe allowed me to get everything turned and lined up with the TBros.
Long story short, I probably won't be in for one of the new headers but I'll keep an eye on developments in case a new 5G batch gets going.
Many thanks to SFDownhill for the Wolf, it is literally like new and sounds great.
