Review on 🔵 MagnaFlow 6in Round Center/Center Straight-Through Performance Muffler Exhaust: Polished Mirror Finish [Model: 14159] by Robert Mac

Installed on a 2014 GMC Sierra with a 5.3 liter engine. I cut out the 3rd catalyst and everything behind it. I replaced the pipe, bent to the factory position, but included this muffler. Now it sounds like a truck, not too loud in the cab etc but has a very attractive rumble both inside and outside the cab.
