Review on High Performance TOTALFLOW 20315 Straight Through Universal Exhaust Muffler - 409 Stainless Steel - 2.25 Inch Inner Diameter Inlet/Outlet by Cedric Ford

I removed the factory muffler and resonator on my 2011 Silverado with 6.2L engine and right after replaced it with a total flow muffler with 12" dynamic range, fell out in front of the rear axle. I was pleasantly surprised it wasn't a wild straight pipe as I basically wanted the truck to breathe! Cuts high rasps very effectively. Growls, Listerine wheezes and low tones are present. Sounds in my opinion this muffler better and less awkward than just straight pipes/muffler removal/bullet muffler/resonator.Cold start is still a bit noisy, idle is perfect and while you're at it it's very noisy.
