It's time to build an exhaust system on the 4.8 Silverado since open headers on a cammed LS isn't exactly streetable. For the exhaust I wanted something that would perform great both now and when the power adder gets installed, but also sound unique at the same time. This required at least 3" exhaust for the single dual sections, and 4" for the single section. I wanted to use one of my favorite mufflers of all time, the Flowmaster Hushpower Pro Series 4" but I had no idea how it would sound with both an X pipe and a Y pipe.
