Review on Flowmaster 42543 2.5-Inch Inlet & Outlet 40 Series Muffler by Francisco Taylor

Product as advertised, sounds much better than stock in my opinion. I have a 2006 F150 with a 5.4 liter V8 Triton engine and am happy with the sound quality of this product. It's worth noting that the black color is pretty bad here. In no time at all it was gone, revealing the silencer's silvery metal housing. The sound is much more aggressive, but the buzz that I like isn't there at all.
