Great Sound, Great System.
I upgraded from the stock exhaust on my Silverado High Country 6.2 liter to the Borla Touring system from the stock system. One of the best decisions ever. The truck looks and sounds terrific. I would definitely recommend this system if you're considering a change. I had the dealer do the install since it was in for scheduled service anyway. It took my tech an hour to do the swap.
I just got the headers on yesterday. It took about 2 hours - all the holes lined up - life is good! Two of the spark plug boots on the drivers side touch the headers, I covered them with insulation, and I'll be looking for aftermarket wires. Seat of the pants dyno, it feels like I picked up a few ponies, It's to soon to tell if I improved my fuel economy
