Hey all I drive an 03 Av 1500, I am in the market for a new exhaust. I currently have the Flowmaster Original 40 series, single 3"/dual 2.5 muffler installed. I was reading some places that flowmaster mufflers aren't the greatest. My current engine mods are listed below in my sig. With the Dynatech's now installed it is loud........real loud......like dragster loud :4:. I like it, my friends like it, people even do a double take to make sure it is my truck making that noise. Loudness doesn't bother me, or the police, cause they haven't pulled me over yet. So my question is, what is the best exhaust, that will give me the most power, and that will integrate perfect with my current setup. In the future, I do plan on supercharging as well.
