Review on 🏎️ Dynomax Super Turbo 17744 Exhaust Muffler: Unleashing Unmatched Performance by Sabryna Wickings

2005 GMC Sierra ext. Cab with 3" tubing. Installed and it hums worse than the 6 year old Gibson set I was trying to replace it with. 1600-2000 RPM So that's in the 55-70 mph range. So everyone's on the Autobahn. A good muffler to be honest. Looking inside the construction looks very solid. I used a Dynomax Super Turbo Cat Back Kit. in the car and loved the sound so I got this one. but for my ears this is not the right muffler.
