Review on 🔊 MagnaFlow Oval Center/Offset Performance Muffler Exhaust 12909 - Straight-Through, 3.5in Inlet/Outlet Diameter, 28in Overall Length, Satin Finish - Classic Deep Exhaust Sound, 5in x 11in by Michael Norwood

Installed at local muffler shop on my wife's 2017 Yukon 6.2L. Easy installation with competent engineering. Only a short piece of pipe is required to connect to the standard exhaust pipe. Sounds great, raspy when starting and accelerating and still smooth when cruising. The noise from the cruise is definitely more than normal but not obnoxious at all. Don't expect a huge increase in performance as the stock muffler is also 3.5 inches, but the sound is what it needs. I have AFM disabled so I don't know the sound of the chopper in v4 mode. that's all. It's not a loud Corsa or Borla Sport, but still very much like an old-school muscle car. Doesn't sound like a new Camaro or Corvette. Much deeper rumble with a big 6.2. It takes some time to break in so it gets a little louder with age, she loves it
