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

I don't do many reviews. This item is so good for the money that I feel I have to give it credit. I have a 2001 built Lb7 Duramax. I had it hooked up directly to a 4" mbrp turbocharged rear exhaust kit. It was too loud and made an awful buzz. This muffler hooked up to my mbrp kit like it was made for it. I just removed the exhaust pipe and it was exactly the length of the flue pipe and fits perfectly in the system literally took me about 20 minutes to put this together sounds great no hum just a low purr.
