I just installed the Borla GM exhaust on my 2017 Z71 Tahoe. FWIW, I love the sound - it was exactly what I was looking for. Not too loud, but loud enough to hear the engine.
I've noticed the average fuel mileage displayed in the info center is about 1 mpg lower since installing the exhaust. I've driven about 60 miles since installing. Do I need to do some reset or will the computer relearn automatically?
I'm sure a small part of the change is taking off faster a few times to hear the exhaust, but I wouldn't think it would have been that much.
