What exhaust system is this?

Looks like Hall's Big Bore system to me.

Can we see a larger version of those pics, say 640x480? From the thumbnails posted it looks like the Hall Big Bore system.

Thanks, guys.
I'll see if I can get a better pic.

Assuming this is the Hall big bore, is it considered a good system for a stock/mild motor?

Depends on who is considering and for what purpose?

It was intended as an inexpensive alternative to stock.

It is usually louder then stock and it is questionable if there is any performance gain from it on a stock engine.

What's good about it? I don't know?

Before my turbos, I ran the Hall Big Bore. It will work quite well. I had no performance issues with that system up to 7500 rpm. It looks small, but it performs quite well. It is loud though, I was heard over 1 mile away.

It resembles the headers that PIM sell.

Headers are Hall Big Bore ... I have a set of headers just like those.

Exhaust (muffler) looks like Hall Big Bore.

Good as a mild upgrade to stock street system. Flows better than the stock (non-GTS) headers.

Hey Dave! Welcome back! Haven't seen you here in a while. Hope all is well.

The Cleveland platform as stock in the Pantera differed from 1971 to mid 1972, the heads in the early version are what is referred to as "Quenched" referring to the combustion chamber design and higher compression ( 11 to 1 ). the second iteration was a hemispherical combustion chamber, this head lowered the compression to ( 8.5 to 1 )due to emission restrictions, that said, the flow is critical from the exhaust side and a good set of high flow headers will improve the performance dramatically, I found the Hall big bore headers restrictive at the collector and inadequate.
