      Review from Magnaflow MF Series Dual Exhaust System - Rear Exit (07-13 5.3L Silverado 1500)

      Awesome Upgrade

      I put the Magnaflow MF Series on my 2013 Silverado 5.3L V8 and it sounds amazing! It's not too loud when you're cruising down the road but when you get into you can hear it. You are able to ride down the road and talk to the person next to you. It's not obnoxious but you can definitely notice it. Highly Recommend!
