Chambered exhaust update....
I didn't finish! :D
It just proves that those who have the most air tools wins. A good air chisel sure would have shortened the process of getting 32 year old pipes apart, which took a good part of Friday to accomplish. No room for a cutting tool and I didn't have a bandsaw, so it was a matter of spreading open the connections in front of the cross member. One chisel and screwdriver are DOA... my bones creak from swinging a brass ball ping hammer... and I'm tired of snorting exhaust pipe rust that kept falling on me in the process.
Replacing the rear monospring was a piece of cake since it was just an even swap. Now I'm waiting on the exhaust wrap(to wrap the monospring) that probably won't be in until mid to late next week.
I have two words about Allen chambered exhaust. First Class! Everything was bent for a good fit with all stainless steel brackets and nice chromed tips. I've still got to drop the exhaust to do the wrapping, so I've just got it *mock* set up underneath. Making the bracket for the rear will take a bit of time since this set-up is for a '73 with a centered tip. They sent a bracket to use for each side, but it will take some modifications to work on this '71. They also told me that. Thanks to Ed T I've got some ideas of what he did.
And if you missed it... the fiberglass mono-spring that was on this vette was shot. I have to assume it was the exhaust being less than 2" away from it. VBP warns to use some kind of heat shield and that anything over 235 degrees could damage the fiberglass monospring. I will do just that.... wrap the mono-spring with fiberglass header wrap good up to 1000 degrees of continuous heat.
By the way Ed T.... I ended up buying a 50ft x 2" wide roll of the header wrap off of Ebay for $19.95. I had money sitting in my Paypal account, so that's the route I took. I should have alot left over if anyone else needs any.

I haven't cranked it up yet as everything it just fit and marked as to how it should go back together. Right now I've got cut 2x4's supporting the exhaust in the rear. Like I said.... I've got to drop it again and I didn't want to press fit anything. Plus, I didn't mention that I went into the garage Friday and smelled gas. The return fuel line from the fuel pump was about to give way completely and was dripping gas. I replaced the hose with a Bubba, but need to hook up the new fuel line.
Ed T....
Glad to hear I am not the only one who has *cave-manned* it. I am well-versed in the typical four letter words again. I was a bit worried that it might look strange without the mufflers in the back when I dropped the exhaust. It looked so empty. But, after I put up the new exhaust just the pipe and the tip makes you forget what was there in the first place.
