Classic Chambered Exhaust

[lippy]

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.

I have the 3" and you'll need it for your HP/TQ to decrease the back pressure. Remember, at highway speeds you'll hear more wind noise than the exhaust. I love my system, size, increased HP & TQ,......and the great noise. Plus, in a Cobra, expect it !

I personally think if anyone complains about the noise, or as far as that goes, wind and rough ride, sell it for a Cadillac.
