Review on 🔊 MagnaFlow Performance Muffler Exhaust 12219 - Oval Center/Offset, 4in x 9in, Straight-Through Design, 3in Inlet/Outlet, 20in Length, Satin Finish - Classic Deep Exhaust Sound by Kurt Ahui

As you know 4.8 is gm's smallest v8. I installed this muffler to replace the mbrp muffler that came with my cat back which was too loud and hoarse when the cats were removed. This muffler has just replaced the mbrp muffler and sounds 1000 times better. At idle, the exhaust is noticeable, but quiet, when driving on the road it is very deep and hoarse. Would recommend this muffler to anyone who wants a great sounding Silverado. I have used many different mufflers and exhaust systems on this truck and this is by far the best sounding one.
