On my 2000, I have a cat back system with a flowmaster 3 chamber muffler. The 2 chamber is too loud for my liking. With the 3 chamber, there is a slight rumble at idle and while cruising. At WOT, it gets much louder!

I've got a 70 series Flowmaster 1x3"in2x2.5"out. They make a system called the ForceII which is what I have. The American Thunder is much louder. Check out

Gibson or Borla will offer far better performance than flows. I have Gibson on my '99 Tahoe and Borla on my '99 Z71 Silverado. Neither is obnoxiously loud (i was 18 a long time ago) but have a solid throaty sound and they both out-perform Flows.
