One exhaust, 2 down pipes. My dealer Ordered through GM, took about 7 days.Also, "Borlas" as in plural? I think I may have made a big mistake.... I ordered "Borla 140775 - 3.50" Into 2.75" ATAK Series Cat-Back Exhaust System" What did you order? Sorry for all the questions... I am 2 weeks away from the truck arriving and so excited about it. Been waiting for over a year, my order started out as a 21 High Country with a lifted suspension and turned into a Z over time...
