I have a 1988 GMC Sierra with a 5.7 liter 350 engine. The engine has some modifications, 2 inch throttle body, larger intake manifolds, performance fuel ignition, and cold air intake. It has about 365 horsepower. It has a nice sound, but I am not completely satisfied with it. I want put on pacesetter headers, two true duals, no cats because it doesn't have to go through emissions anymore.I'm a little confused about what muffler i want. I have three options, Flowmaster Super 44, Flowmaster Series 10, or glasspacks. The Flowmaster series 10 has the loudest sound and deepest rumble but if anyone has any expert advice it would be greatly appreciated,
Thank You
