I have the Chambered II system, love the sound and it get's compliments everywhere. The Stage II you show is a little quieter (between stock and Chambered II). The Chambered II is nowhere near as loud as some of the other chambered systems out there. The I & II denotes how many mufflers per side.
Allen's has good quality parts and they fit well, if not he backs everything up. The exhaust pictured is for manifolds, but he can include front pipes for headers that may need modification. I fabbed my own front pipes for better clearances. I used a '73 2 1/2" inch system with 2 1/4" tail pipes.
He usually includes stainless tips with the Chambered II.
There will be some that say chambered systems are restrictive, the originals were, but the internal pipe size used today is larger than the originals. There are no dyno tests to prove any restriction theories on modern chambers.

I hope you will be running headers with the 383. I would have a custom system built for your motor. If you are going to be putting out anywhere near 450+ HP the system shown will not flow enough. It will work but your HP will suffer. I have a custom 2 1/2 system that should support 500 HP 383. I'm probably just shy of that now. The custom system fit better than any per made system I had on the car.

Yes, headers will be in the mix for sure.

well..between civil servants delaying my passport application (had to get a new super fancy one because of the much more stringent checkls) and terrorists messing things up, not enough time to make it to detroit for the woodward cruise...I cancelled, no use in going to the US and drive around... I wanted to go to woodward & carlisle.
