I just put a set of chambered exhaust on my 72, change it over from side pipes. I looked an M/A and other places, but I have a vett friend tell me he got his from Allen's Exhaust, they make the chambered exhaust for M/A and several other Vett supply houses. I called Allen's for a price and he sold me the pipes, W/ packings, bezels, tips, hangers and clamps for a great price. All most have it installed. So far very happy with them.

I have it (aluminized version) and I love it. I get lots of compliments with it. It is however, on the louder side. I live in a group of townhouses and I have to be careful not to peddle it too much if I decide to drive it to work and leave at 7:00 am. Dont want to bug the neighbors too much I set off a car alarm as I drove by once also. (i was in a tight downtown neighborhood).
I just purchased a set of the gal. alu. ones...as I felt they would last my life time...(G) When we 1st fired the a car up...I thought OMG...what have I done...of course with a smile on my face. And in the garage they really raddled the windows. But now I like to start the car..just to hear that sound. Idle sound is music to my ears....LOL...and I never thought I would be the loud pipe kind of guy...but I am hooked! To each his own music...LOL

Drive it like you stole it!
I also have Allen's exhaust on mine. I replaced old/tired flow masters. I probably liked the flowmasters better on idle, but on highway with the chambered; I did get exactly what I wanted; throaty/raw music that screams power.
They are loud (louder than flowmasters) and I have also triggered car alarm systems in parking lots (which is kind of fun)...
Came with all the clamps, hangers and nice chromed tips. I had it installed at a local shop since I was replacing my headers at the same time and I don't do welding.
Note on this (in case you do similar); if you are replacing the headers at the same time and get black painted ones; there's a "burn in" procedure to follow. I was not aware of it and did not follow it. Within 30 minutes, smoke came out of the hood; the paint of the headers pretty much all burned. So brand new headers looked like 15 years old headers on the first drive and a few months later (without protective coating); were covered in surface rust.
