            Review from Magnaflow Off Road Pro Series Single Exhaust System - Turn Down (14-18 5.3L Silverado 1500)

            Exactly what I hoped for

            Thanks to American Trucks, I was able to decide on this particular exhaust. Without their great install video, and sound clips throughout their product page, I’d probably still be searching for the right exhaust. From start to finish, install took me maybe 45 minutes. My Silverado is lifted 7”, so to avoid using any jacks or a lift, I simply removed the factory spare tire and the OEM exhaust slid straight out the back of the truck. Sound is very deep while cruising, but almost factory sounding at idle. Quality of parts is on par with you’d expect from a company like Magnaflow, and everything bolted up easily.
