Any new users/additional experience with the Classic Chambered CobraPacks?
I'm considering using either the 2.5" x 24" or 3" x 24" with the 482 SO (600 HP +/-) Brent is building for me. I am specifically interested in the noise levels at highway speeds for the 2.5" and 3". Obviously the 3" is less restrictive, but I'm thinking the 2.5" may be easier from a noise perspective yet a big flow improvement over stock.
