Two chambers are good and not too noisy, the one chamber are a bit noisier. But if that's what your looking for, the super 10 series are wake the dead.
Two chambers sound great, If you really want to hear your exhaust system from both inside and outside of the vehicle, the 40 Series is good for that.
The 44 Series is the same as the 40 series but is quieter on the inside but just as noisy as the 40 on the out side.
I was running the 40 Series before i went with the Magnaflows, they were on special clearance that week
and have been happy with them ever since. Note: that i would not put anything larger then 2.50 inch pipe from the Cat back. Anything larger and your going to loose HP and lower end torque, which is what you want since your truck is govern to 96 MPH so really you need more torque then HP for your 4.8.
