Review on 🚗 Upower 4-Inch Inlet Diesel Exhaust Muffler 7x24 Body: Straight Through Stainless Steel Resonator Muffler XS2772 by Dean Wilson

I don't do many reviews, but since it is related to the sound of your truck, I absolutely have to. The damper seems to be well made. Exhaust clamps must be ordered separately. Installation took about 20 minutes, I have a 2014 Cummins and I placed the muffler just in front of the rear flight deck door. As for the sound, it sounds deep and hoarse. The volume is about half that of a 4" turbo in the rear with a 6" tailpipe. During a test drive, I noticed that there was no grinding noise when accelerating hard and there was very little internal hum when cruising. and all I am satisfied with the product. However, this will surely take some time to get used to. * Make sure you start your truck before installing the muffler. I started this after cutting out part of the pipe and as you can see in the second part of the video the rest of the sanding came from the second cut on the back. *
