I've done lots of research online while trying to find what would be the perfect exhaust set up for a truck with the 5.3 v8. So far I haven't found anything on which kind of full set up would be the best for a daily driven truck with no major mods to it. What setup would lead to having the most low end-mid range torque/horsepower? The setup I've bought and will be installing soon is 1 3/4 long tube headers, y pipe, no cats, to a single borla xr1 muffler. The piping diameter will all be 3 inches. Based on my research this sounds like the absolute best setup. I just want to know everyone's own thoughts on if this sounds about right or if there is a better setup. This should give me the right exhaust velocity for low-mid range as well as a very free flowing setup with little back pressure so it all comes out free and fast!
