I am thinking about replacing the exhaust system on my 66 Monaco and I ran across this vendor http://waldronexhaust.com/cart/ has anyone purchased from them? Loooks interesting...

 

I don't know, seems a fair price I guess, but the text is confusing. Is it a dual or single system? It says it will fit a dodge but they have no listing fotr a chrysler and the exhaust would be the same. $400.oo and you still have to pay shippig and put it in. If you need it put in for you, more money. What if there are fitmant issues? You should be able to find a reputable shop loaclly that would install a complete system for that price. Look around locally for an older shop and talk to folks in your area that have vintage cars, maybe even a couple car cubs, to get references.
Edit: I went back to the site and could not even find the system your link supplied the first time. Typed in Dodge and got a bunch of vintage stuff all single systems. (?)
