Allen's chambered exhuast
We recently talked about Allen's mufflerless chambered exhaust systems. http://www.allencorvetteexhaustsystems.com/
Question is what's the difference between
Chambered-1
or
Chambered-2
Only difference I can make out is more chambers on #2. So is #2 more restrictive? I'm pretty much set on the Aleens chambered system but which and also whether I am going to ceramic coat the pre-existing hedman headers or purchase new already coated headers?

You are correct, the difference is the "extra" chambering. I talked to the guys at Allen's a couple weeks ago, and was told many prefer the sound. Give 'em a call, they're very friendly and have a few extras they don't mention on their website.

Re: Allen's chambered exhuast (73 Vet)
I agree with 73 Vet. It looks like system #2 has chambers on the rear pipes. No doubt to quiet things down a bit. But system #1 as I have is not excessively loud although some may not enjoy a noise level that is non-stock.

I'll probably shoot for system #1. Allens does not make this for header applications so I'll probably go with manifolds. AnthonyLT1 has a new set for sale.

FYI: I have #1 on an otherwise stock '72 LT-1 and love the sound. It may seem loud at first (compared to stock mufflers), but you and your neighbors will get used to it... :D

Re: Allen's chambered exhuast (SharkAttack)
I'm still debating on going to manifolds for originality sake plus several members have said that manifolds increase low end torque.

They offer the system for headers and they are about $100 cheaper across the range. I have been looking into chambered systems for a while and am still undecided.
